Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How are DNA and RNA similiar?
A
They have nucleotides.
B
They have the same sugar.
C
They have the same bases.
D
They are double strands.
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.

Detailed explanation-3: -So, the three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
