Question

What is the common point of similarity between DNA and RNA?

• A. Both are double stranded
• B. Both have identical sugar molecules
• C. Both have identical pyrimidine bases
• D. Both are polymers of nucleotides

Answer 1

Answer: (D)

Both are polymers of nucleotides

DNA and RNA both are polymers of nucleotides. They are long polymers made from repeating units called nucleotides. The strands are known as polynucleotides which are the chain of nucleotides. Each nucleotide is composed of a nitrogenous base, monosaccharide sugar and a phosphate group.

Thus, the correct answer is option D.
