Question

Genes, chromosomes, and DNA are important structures for processes related to heredity and reproduction. How are these structures related?

A
Many chromosomes make up a gene, and many genes make up DNA.

B
A chromosome is the same thing as a gene and both are made of DNA.

C
DNA is made up of chromosomes, and chromosomes are made of genes.

D
Genes are sections of DNA that make up a chromosome.

Answer 1

Chromosomes are made up of genes, and genes are made up of DNA.

Step-by-step explanation:

Chromosomes are coiled structures made of DNA and proteins. They contain genes, which are the units of genetic instructions for making proteins. Most genes contain the instructions for a single protein and there may be hundreds or thousands of genes on a single chromosome. DNA is the hereditary material and is made up of chromosomes. So, chromosomes are made up of genes, and genes are made up of DNA.

Answer 2

C

DNA is made up of chromosomes, and chromosomes are made of genes.
