Both evolutionary biology and genetics have their roots 150 years ago in work with phenotypic variants of plants and animals. In contrast, microbial genetics originating as recently as the 1940s, rapidly revealed that filamentous DNA molecules are th....

Beginning with an exception to normal function caused by a genetic aberration, one may hope to find at least one protein with non-redundant function in a certain biological process. This approach permitted the identification of the receptor for bacte....

Telomeres protect chromosome ends and help stabilize the genome. Throughout human life and in aging, telomeres often erode down, eventually causing cells to malfunction or die. The highly regulated cellular enzyme telomerase adds telomeric DNA to tel....

When Monsanto first tried to introduce GMO seeds into Europe there was a backlash by the Green parties and their political allies, who feared that American agro-business was about to take over their food supply. Thus began a massive campaign not agai....

The diagnosis, classification, and treatment of human cancers are being transformed by scientific discoveries that were strongly influenced by the discovery of the c-src proto-oncogene, as described in the lecture by Michael Bishop. The path to this ....

In 2010, we chemically synthesized the 1078 Kb Mycoplasma mycoides genome and transplanted it into a recipient cell cytoplasm to create a 'synthetic cell', JCVI-syn1.0 (Science, 329, 52-56, 2010). We identified several hundred non-essential genes by ....

The complexity of modern biological life has long made it difficult to understand how life could emerge spontaneously from the chemistry of the early earth. We are attempting to synthesize simple artificial cells in order to discover plausible pathwa....

A discussion of the problems caused by genetic engineering.

This episode covers the symptoms and theorized causes of the Autism Spectrum Disorders.

This episode outlines details about Wilson disease, a rare disorder involving the amounts of copper in the body,  and the negative effects on vision and different organs.

The importance of transcription in cells and its effect on disease.

Intracellular synthesis is immensely fast and complex.
