Explain how the sequence of nucleotides in DNA determines the sequence of amino acids in a protein.

• By matching one nucleotide with 3 corresponding amino acids

• Through the formation of peptide bonds between nucleotides

• By determining the order of codons, which specify amino acids

• By directly synthesizing amino acids from DNA segments
