NEET BIOLOGY

Detailed explanation-1: -A nucleotide is the basic building block of nucleic acids (RNA and DNA).

Detailed explanation-2: -Nucleic acids come in two natural forms called deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Nucleic acids are made of biopolymers, which are naturally-occurring, repeated sets of monomers (making polymers) that then create nucleotides, which form nucleic acids.

Detailed explanation-3: -A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins.

Detailed explanation-4: -DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a nucleic acid, DNA or RNA. Each nucleotide is made up of three components: a nitrogenous base, a pentose (five-carbon) sugar, and a phosphate group (Figure 5.2).

Detailed explanation-5: -Among biomolecules, nucleic acids, namely DNA and RNA, have the unique function of storing an organism’s genetic code-the sequence of nucleotides that determines the amino acid sequence of proteins, which are of critical importance to life on Earth.
