Although viruses and bacteria are very different types of microbes, both have genomes made of nucleic acids. These nucleic acids contain the instructions necessary for cells and viruses to exist and reproduce. But since bacteria are living cells, the expression of their genes directs a...

There can be no doubt that the prickliest issues in modern genetics are not scientific ones. Ethicisits and geneticists both find themselves forced to examine and reexamine assumptions society makes about people. It is assumed, for example, that all men are created equal, to some...
Tumor suppressor genes
