Compare and contrast the four major functions of genes.
What will be an ideal response?
The ideal answer should include:
1. Genes are used in four different processes that enable various functions critical to development.
2. Genes are used to make proteins. The DNA sequence is used as a template for making proteins in the cell.
3. Genes duplicate themselves. The DNA sequence is duplicated when a cell divides by mitosis, an essential process in the growth of the body.
4. Genes enable sexual reproduction. Each chromosome pair duplicates itself and gamete cells are formed containing one of each pair of chromosomes (23 total) in the sperm cell and the ovum. These combine during fertilization to produce a zygote with 46 chromosomes that mingle the father's and mother's DNA.
5. Genes are used to regulate other genes.
