MCQ
Genetic information in a $\text{DNA}$ molecule is coded in the:
  • ✓
    Sequence of nucleotides
  • B
    Base pairing
  • C
    Turning pattern of the helix
  • D
    Portion of each base present
✓

Answer

Correct option: A.
Sequence of nucleotides
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 $\text{DNA}$ molecule is coded in the sequence of nucleotides.
