YOU AND YOUR GENES.
WHAT ARE GENES?
Every living organism is made from cells. Most cells have a nucleus. Inside the nucleus are chromosomes. Chromosomes are made from a chemical called DNA!
Chromosomes contain thousands of genes. Genes carry information that controls what an organism is like. Each gene determines one characteristic. The information in a gene is a set of instruction for making proteins, including;
-structural proteins - to build up the body.
- enzymes - to spped up the chemical reaction.
