Similarity in DNA and RNA :

Similarity in DNA and RNA :
A Both are polymers of nucleotides
B Both have similar pyrimidines
C Both have similar sugar
D Both are genetic material

Detailed Solution

Both DNA and RNA are nucleic acids, i.e. polymers of nucleotides joined by phosphodiester bonds.
They differ in their sugar (deoxyribose in DNA, ribose in RNA) and in one pyrimidine (thymine in DNA, uracil in RNA). DNA is the genetic material in most organisms, and RNA only in some viruses.
So the similarity is that both are polymers of nucleotides.
