Question

The information carried by DNA is incorporated in a code specified by the

• A. Phosphodiester bonds of the DNA strand
• B. Number of separate strands of DNA
• C. Specific nucleotide sequence of the DNA molecule
• D. Number of bases in a DNA strand

Answer 1

The correct option is C Specific nucleotide sequence of the DNA molecule

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.

Thus the correct option is C.
