Cut outs of DNA by shapes.... I'm bragging! This is cool! NO NUMBERS! Just shapes and colors to draw molecules. Since CHON are used exclusively for amino acid backbones (and P for RNA-DNA)and each has a unique number of bonds the shapes correspond to the number of bonds! Just look and learn (or DRAW n' LEARN) (You can correctyourself and I show by my mistakes and second guessing....)See ....ScienceIsGOLDen.com ....for printouts you can just color in, connect the dots, even trace it out and hang on the refridgerator!...This is what the kids in college don't fully get, THE CHEMICAL Structure...the lines they use are boring and not very descriptive AND IN BLACK AND WHITE...We need to use color and the 3rd DIMENSION! this is hokey but again you can draw this on a napkin so it's practical!

Chargaff's Ratios


Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure. Originally created for DNA Interactive ( www.dnai.org ). TRANSCRIPT The DNA molecule is made up of very long chains of the 4 bases: A, C, G and T. In 1950, Erwin Chargaff published a paper stating that in DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This is known as Chargaff's ratios and it was a crucial clue that helped solve the structure of DNA. Chargaff's ratios are universal: all forms of life obey this rule. Only the balance of AT pairs and CG pairs varies between species.

DNA 3D Structure Model with labels


This is a quick and dirty model that I created in Maya. The deoxyribose nucleic seen here represents a basic interpretation of the chemical bonds that would be present in a single strand or double Helix. I colored the anti parallels both red and blue to simulate their adjacent qualities as they spiral upwards and string along and bond the genes themselves. The genes can be seen as Thymine and Adenine/ Cytosine and Guanine. These are the only formations these gene patterns can form therefore, Thymine will only bond with Adenine, and Cytosine will only bond with Guanine. Not appearing in this animation are the basic hydrogen bonds that connect the nucleotides. Also note that the genes coils themselves are elongated and therefore are NOT supercoiled. Well thats enough yammering, the background tune is provided by "The Octopus Project"

First deoxyribos sugar then Phosphate and Nitrogen base come in. The nucleotides are in groups of two Prymidines and purines too. Prymidines are the smaller base Thymine and Cytosine are what they incase DNA Purines base is bigger than the other Adenine and Guanine are what they cover the strands are complementary DNA A base pairs with an outside group some people just see an alphabet soup. Adenine and Thymine bond together for fun Guanine and Cytosine do too. Hydrogen bonds the bases together another element just wouldn't be better The DNA replicates to make some more the body's in need of a very large store The DNA helicase is what is used to unzip the DNA into 2. The replication fork is where it sits making space for the RNA to fit The RNA can't stick around alone It needs a friend to stay at home DNA The polymerase is the friend in need without it, the DNA can't succeed. It glues the RNA into place DNA You can't read DNA up and down If you could it would cause a frown The leading strand is read and cannot hide 5-3 prime and thats just one side The lagging strand gets read last 3-5 prime and it gets done fast All of this is done automatically Its all done perfect and carefully DNA Thats all there is to know about DNA <b>...</b>

1. Strands are separated by the enzyme helicase 2. DNA binding proteins keep the strands from reattaching 3. New DNA is made at the leading strand by DNA Polymerase 3 from 5 prime to 3 prime 4. RNA Primase lays down a RNA primer at the lagging strand 5. DNA Polymerase 3 lays down new DNA in the lagging strand 6. Step 5 is repeated 7. Polymerase 1 replaces the RNA primers with DNA 8. DNA Ligase links the lagging strand There are four nitrogenous bases, which are Adenine, Guanine, Thymine, and Cytosine. Adenine always bonds with thymine and cytosine always bonds with guanine.

DNA Structure


"Two DNA strands intertwine to form a double helix. Each strand has a backbone composed of phosphates and sugars to which the bases are attached. The bases form the core of the double helix, while the sugar/phosphate backbones are on the outside. The two grooves between the backbones are called the major and minor groove based on their sizes. Most proteinDNA contacts are made in the major grove, because the minor groove is too narrow. The DNA backbone is assembled from repeating deoxyribose sugar units that are linked through phosphate groups. Each phosphate carries a negative charge, making the entire DNA backbone highly charged and polar. A cyclic base is attached to each sugar. The bases are planar and extend out perpendicular to the path of the backbone. Pyrimidine bases are composed of one ring and purine bases of two rings. Adjacent bases are aligned so that their planar rings stack on top of one another. Base stacking contributes significantly to the stability of the double helix. In a double helix, each base on one strand is paired to a base on the other strand that lies in the same plane. In these base pairing interactions, guanine always pairs with cytosine, and thymine with adenine. A GC pair is stabilized by three hydrogen bonds formed between amino and carbonyl groups that project from the bases. In contrast, an AT pair is stabilized by two hydrogen bonds. The specificity of base pairing—that is, C always pairing with G, and A always pairing with T—ensures <b>...</b>

Methyl group drip, STAT!


pseudoscience, or bastardized real science, someone, not sure it is Inmendham, is fucking confused! Lets trip a few reality genes: We can identify, with the use of dye, the "turned off" genes. We can turn off a gene, in fact, simply by the addition of methyl groups to the DNA, at CpG sites (CpG sites are regions of DNA where a cytosine nucleotide occurs next to a guanine nucleotide in the linear sequence of bases along its length.), to convert cytosine to 5-methylcytosine. In the example on the video, coat color is a tag. The same process with an additional obesity tag has been produced in mice using environmental toxins: Interestingly BPA, the toxin recently reported in certain plastic baby and water bottles. The results were a lot scary! The change was passed on to the off spring. Normally brown mice born to a cloned mother with the obesity gene turned on and a yellow coat tag, were born with the yellow tag and obesity gene turned on. Pregnant and drinking bottled water? Your off spring may well have a stake in what is in that plastic. Once turned on, you can pass the awakened gene along. DNA and genes are NOT changed. I don't think it is evolution. We are talking about on off switches within the same unchanged DNA and genes. Will you have a tail and no limbs, or brown eyes and ten fingers as a human? The truth is you probably have the genes for either, it is more determined by the proper genes turned on telling your body you are supposed to be a human, not a bacteria <b>...</b>

DNA Replication Song


A song about DNA Replication, based on Backstreet Boys' "I Want It That Way." Lyrics originally written by these guys www.youtube.com (adapted by Mr. Hsu). Online song performed by and Powerpoint slide show done by a simple high school science teacher named Mr. Hsu (live song performed by Mr. Moore and Mr. Hsu). mp3 available: c3po.barnesos.net This song and video have been made solely for educational purposes. Its level of depth and detail into the process of DNA Replication are aimed at High School Biology students (at least the ones I teach). If you find any errors or omissions (ie I didn't mention Primase), this is due to the fact that I'm not teaching college-level Biology AND I'm being constrained by describing such a complex biochemical process through a fairly old pop song with incredibly repetitive lyrics. Mr. Moore and I actually performed this song as a duet for out students in class the day before spring break. If you're lucky, you might find a video of such a live performance somewhere in the vast internet (quite a few of them were recording me singing it in class, after all). This video is a result of me taking a simple digital camera and aiming it at my computer to try and record the performance my students experienced (so sorry for the crude recording and poor quality). I have recorded an mp3, and if I have time, I will find a place to upload it for public download, so that other Biology students can listen and study for their tests on DNA Replication <b>...</b>

Protein Synthesis Rap


For Mr. Farnan's 5th Period Honors Biology Class. This is my Protein Synthesis Project. Lyrics: Synthesis of protein You get the amino acids from cuisine First, a message is sent to the cell. It enters the nucleus, and rings like a bell. The DNA unwinds, to show the gene. And so m-RNA is made, so very keen. With Nucleotides, and RNA polymerase. Then, the m-RNA starts picking up a pace. This process is known as transcription. It's just like someone ordering a prescription. Any parts that aren't used. are called introns and should be losed. Only the exons affect the final production. Anything else undergoes deduction. Chorus: Adenine to Uracine. Guanine to Cytosine. That's how they pair. Anything else is rare. m-RNA leaves the nucleus through nuclear pores. Depending on the message, there might be more. In the Cytoplasm, it binds to a ribosome. m-RNA enters it, like a home. The message is then decoded. 3 bases at a time (codon), then the corresponding amino acid is goaded. Activated through an enzyme. Onto a t-RNA then it climbs. It hides in the binding site. The anticodon (three nucleotides) under it acts like a kite. It's dragged towards the ribosome, and the anticodon binds. As long as it pairs with the correct codon, it doesn't mind. Chorus Another codon is read. And another t-RNA with an activated amino acid is led. A second t-RNA comes and picks up another acid. Does the same thing, pairs up with a codon, it's quite lucid. The first t-RNA then escapes. It's amino acid <b>...</b>

Nucleotides consist of a) sugar, b) nitrogenous base, and c) phosphate 2. Nucleosides consist of aa) sugar and b) nitrogenous base 3. The sugars of nucleosides and nucleotides are either ribose (found in ribonucleotides of RNA) or deoxyribose (found in deoxyribonucleotides of DNA). 4. The nitrogenous bases found in nucleotides include adenine (purine), guanine (purine), thymine (pyrimidine), cytosine (pyrimidine), and uracil (pyrimidine). 5. The bases adenine, guanine, and cytosine are found in both ribonucleotides and deoxyribonucleotides. Thymine is almost always found in deoxyribonucleotides. Uracil is found primarily in ribonucleotides and rarely in DNA, but does appear as a deoxyribonucleotide intermediate in thymidine metabolism. 6. Ribonucleotides are the building blocks of RNA and deoxyribonucleotides are the building blocks of DNA. 7. Nucleotides and nucleosides are made in cells by two general mechanisms - salvage pathways (use breakdown products of other nucleotides/nucleosides) or de novo pathways (synthesize nucleotides/nucleosides from scratch <b>...</b>
