The image shows how information flows among DNA, genes, chromosomes, and proteins in a cell. Based on the image, which three options correctly represent the relationship between the given components?

• Genes are stretches of DNA that instruct the formation of proteins showing different traits.

• A chromosome has different genes that can code for different proteins showing different traits.

• A chromosome has different genes that can code for different DNA molecules showing different traits.

• Protein-coding genes are stretches of DNA that instruct the formation of chromosomes showing different traits.

• Chromosomes are a compact form of DNA that contains genes that instruct the formation of proteins showing different traits.
