 Biology Study Material in What is a gene?

• A chromosome is made up of a large molecule of deoxyribonucleic acid (DNA). A small section of DNA is called a gene. Therefore, a large DNA molecule that makes up a chromosome contains thousands of genes.]

• Genes hold coded instruction called the genetic code. This is passed from the parent to the offspring. This genetic code controls cell activity and information to specify the characteristics of the organism.
