Hemoglobin is a protein in red blood cells that carries oxygen throughout the body.
What factor most directly determines the sequence of amino acids that form hemoglobin?
A.The type of sugar molecules in the cell, which dictate how proteins are built.
b.The number of ribosomes present in the cell, which determines the rate of protein synthesis.
c.The amount of oxygen available in the bloodstream, which affects protein structure.
d.The sequence of nucleotides in DNA, which provides the instructions for assembling amino acids.

The factor that most directly determines the sequence of amino acids that form hemoglobin is:

d. The sequence of nucleotides in DNA, which provides the instructions for assembling amino acids.

This is because the DNA sequence is transcribed into messenger RNA (mRNA), which is then translated into a specific sequence of amino acids in proteins like hemoglobin.
