SSC MTS EXAM

Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T).

Detailed explanation-2: -phosphate groups, guanine, and thymine. DNA and RNA are both nucleic acids.

Detailed explanation-3: -Similarities Between DNA vs RNA Molecules For starters, we can easily note that they are both types of nucleic acids, chainlike molecules composed of nearly identical units called nucleotides. Individual nucleotides are called monomers, while the linked together molecule is called a polymer.
