Answer: (1) A chromosome is composed of many genes.
A gene is a sequence of DNA, which are instructions on how to make proteins for the cell. Proteins are then used as building blocks to make tissue or other essential things the body needs. Those proteins also determine things like a person's eye color. Each gene has a stop and end point. When you bundle a bunch of genes together, you form a group known as a chromosome. Each chromosome has a different role to play, so not all chromosomes carry the same information.
