Genes are the working parts of DNA – the vast chemical database that forms the blueprint for humans, animals, plants, insects and bacteria. Both humans and microscopic worms have about 19,000 genes (only about a QUARTER the number of people at a Man. U. match!).We share about:
98% of our genes with an ape
80% with a mouse
50% with a fruitfly
20% with a tiny worm
Genetics is the study of genes and the chromosomes that house them:
How do genes work?
How do mistakes in genes cause disease?
How are they passed on from generation to generation
