What is a chromosome? How does it relate to DNA? What is the relationship between a gene and a chromosome?

• An X that holds DNA and is found somewhere inside your body.

• A tightly wrapped ¨X¨ made of DNA, and a gene is a segment of DNA that codes for a trait.

• A line made from multiple nitrogen bases.

• A thing found in the nucleus that can code for traits and hold your DNA.
