People have different ideas.These days,most people agree that the answer to the question is yes.Recent studies have shown that genes especially influence our self-control and our sense of purpose.What is a sense of purpose?If a person really wants to complete something...
Extrapolating to a genome containing 30,624 genes, this implies there are 4190 genes that influence the body weight of the mouse. We suspect that even this large number may be an underestimate because some mice in the "no information" and "not viable" categories probably have altered body ...
been trying to understand the human body for a long time.In I860,Mr Mendel discovered why we look the same as other people in our family.It is because of small things called "genes"(基因) in our body.In 1953,two scientists,Watson and Crick,found out that those small parts are really...

There are two similar genes in the bodies of mammals.By changing the function of on gene,scientists extended the life of a mouse by 1 8 per cent(or 4.5 months).Another gene is called IGF-1.Researchers still don’t know how it affects our body.But by reducing its functions the life of...
