Things We Still Don’t Know about Genes

From the horse’s mouth of geneticist Axel Kahn, the reader is introduced to the world of living cells and genes. Genes are what make organisms of the same species resemble each other, and yet at the same time remain unique. Biologists thought they knew a lot about them, but as research yields more and more results, the results bring up more and more questions.For example, among the genes that play a part in the occurrence of illnesses, researchers cannot always determine to what degree each individual gene is responsible or how the genes interact. Lots of questions remain.
