Question

Amino acids are small molecules that make up proteins.

What information do genes determine when building proteins?

choose all that apply:
1)the amino acids that are used.
2)the order of the amino acids.
3)the location where the protein is built.
4)the total number of amino acids.

Answer 1

mRNA provides the instructions for which amino acids are used (codons do this), the order of amino acids (the codons are read in a specific order), and how many are used (stop codons control the length of the protein).
1,2, and 4 (not sure about 3)

Answer 2

2, the order of the amino acids
