Unit 3 EOU Review

What is the relationship between DNA, a gene, and a chromosome?

• A gene is a segment of DNA. DNA coils tightly together to form a chromosome.

• A chromosome is in DNA. Genes are part of chromosomes.

• DNA is a segment of a gene. Chromosomes coil tightly together to form a gene.

• DNA is in chromosomes. Chromosomes are part of a gene.
