Genetics

... the easy amplification of DNA 1989 The first human gene is sequenced by Francis Collins and Lap-Chee Tsui , it encodes the CFTR protein, defects in this gene cause cystic fibrosis 1995 The genome of Haemophilus influenzae is the first genome of a free living organism to be ...

Human

... females have the sex chromosomes XX and males have XY. The X chromosome is longer and carries many genes not on the Y chromosome, which means that defects of X-linked recessive genes affect men more often than women. For example, genes that control the clotting of blood reside on the X chromosome. ...

Memory

... of memory is known as amnesia . There are many sorts of amnesia, and by studying their different forms, it has become possible to observe apparent defects in individual sub-systems of the brain's memory systems, and thus hypothesize their function in the normally working brain. The physiology of ...

Promoter

... sequence and susceptibility to hundreds of diseases , it requires a sophisticated search strategy to extract those diseases that are associated with defects in transcriptional control where the promoter is believed to have direct involvement. This is a list of diseases that evidence suggests have some ...
