Which of the following codes for proteins? Enzymes RNA chromosomes genes

The best answer is that Genes code for proteins!

Chromosomes is where the genes are located (humans have a lot less chromosomes than genes)

Enzymes are chemical substances that participate in the creation of proteins.

RNA is another molecule which is important for making of proteins, but it is more fitting to say that the Genes are the ones coding for proteins. (RNA participates in the coding and decoding of genes)
