Question

What do genes do?

Answer 1

Genes:

1. Genes are made up of DNA and the physical and functional unit of heredity and part of the chromosome.
2. One chromosome contains DNA which is made up of many genes.
3. Each gene contains a set of instructions for a protein-coding or any particular function.

Functions of genes:

1. Genes carry genetic information from the parent to the progeny.
2. Genes control the functions of DNA and RNA.
3. Genes have a set of instructions for each function.
4. Genes have specific codes for the production of each protein.

Example:

1. Globin gene contains a set of codes for the production of haemoglobin.
2. Thus, the globin gene instructs for the production of haemoglobin.
