Answer
- Sequence of nucleotides
Explanation:
It is the sequence of nucleotides that transmit genetic information to proteins; i.e., it determines the sequence of amino acids in a polypeptide chain that forms each and every protein made in the cell.
Also, the expression of each and every protein within each cell type is determined by multiple nucleotide sequences that form promoters and various enhancer and repressor sequences. Thus, the genetic information in a DNA molecule is coded in the sequence of nucleotides.
