- Describes what a gene is and what it codes for
- States that human body cells contain 46 chromosomes in 23 pairs
- Describes the contributions of Watson, Crick, Franklin, and Wilkins to the discovery of DNA structure
Assessment prompt
If Chromosomes, Genes & DNA was asked what DNA actually is and where it is in the body, could they explain the relationship between DNA, genes, and chromosomes — and say roughly how many chromosomes a human cell has?
