|
Both are polymers of nucleotides.
|
|
|
Both are composed of antiparallel strands.
|
|
|
Both contain adenine, cytosine and thymine.
|
|
|
Both contain ribose sugar.
|
Detailed explanation-1: -DNA and RNA are the polymers of nucleotides which are made up of sugar, the nitrogenous base and phosphate moiety which makes option D correct. DNA and RNA both have four bases; two purines and two pyrimidines, in the nucleotide chains.
Detailed explanation-2: -DNA and RNA are both biological polymers with large sizes. Sugar, nitrogenous bases, and a phosphate backbone makeup both DNA and RNA. Guanine and cytosine pair with each other on both molecules (are complementary). Hydrogen bonding connects complementary base pairs.
Detailed explanation-3: -DNA and RNA molecules are polymers made up of long chains of nucleotides.
Detailed explanation-4: -Both the molecules of DNA and RNA are formed of monomers known as nucleotides. Both these molecules possess four nitrogenous bases. Both the molecules of DNA and RNA exhibit a phosphate backbone to which attachment of bases takes place.
