Dehydration synthesis is used to connect monomers into polymers and hydrolysis breaks them down again. The major characteristics of nucleic acids are described as well as there directionality from 3' to 5' end. Protein structure is describes as well as the structure of its monomers; amino acids. The carboxyl and amino ends of a protein are described. The major groups of lipids are included with a brief discussion of saturated, unsaturated and trans fats. Finally carbohydrates and their sugar monomers are discussed.

By Bruce lipton Recent advances in cellular science are heralding an important evolutionary turning point. For almost fifty years we have held the illusion that our health and fate were preprogrammed in our genes, a concept referred to as genetic determinacy. Though mass consciousness is currently imbued with the belief that the character of one's life is genetically predetermined, a radically new understanding is unfolding at the leading edge of science. Cellular biologists now recognize that the environment, the external universe and our internal physiology, and more importantly, our perception of the environment, directly controls the activity of our genes. This video will broadly review the molecular mechanisms by which environmental awareness interfaces genetic regulation and guides organismal evolution. Bruce Lipton

DVD Description Our Biotechnology DVD first looks at major research areas in biotechnology such as the Human Genome Project and the various forms of recombinant DNA technology that produce transgenic plants and animals. The program then goes on to look at the tools used by biotechnologists such as restriction enzymes, plasmids, vector and vector less insertion of genes into genomes, and the production of genes via polymerase chain reactions. The program then concludes by looking at the future of biotechnology and some of the environmental, economic, and ethical issues raised by biotech.

Every child needs a father' is a phrase heard often enough, but is there any evidence to support it? In this enlightening documentary, child psychologist Laverne Antrobus goes on a quest to discover why a dad's relationship with his offspring is so important. She uncovers fascinating new research which is shedding light onto the science of fatherhood. Laverne meets a new dad who is experiencing Couvade Syndrome, a condition sometimes known as 'sympathetic pregnancy'. She is keen to explore if the symptoms - which are similar to those felt by pregnant women, such as nausea and sickness - might be physiological as well as psychological. The dad takes a blood test shortly after the birth of his third child and Antrobus discovers that hormones could be the cause of his symptoms: possibly nature's way of 'priming' him to become a more nurturing father. Laverne then meets one of the UK's leading experts in the father's role within the family. While observing father and toddler play in his lab, she finds out how the rough-and-tumble play they witness is classic 'dad behaviour'. It is believed that this type of fatherly play is essential in teaching toddlers the boundaries of aggression and discipline. In the final investigation, Antrobus looks into recent research which claims that men who have a good relationship with their daughters can influence the kind of husband the daughters choose. The study also found that girls whose fathers were absent during their formative years <b>...</b>
