Question

Purines and pyrimidines polymerise to form

• A. Nucleoside
• B. Nucleic acid
• C. Ribonucleotides
• D. All of the above

Answer 1

Answer: (B)

Nucleic acid

Nucleic acids are polymers of nucleotides. They are formed by joining together of long chains of nucleotides. RNA (ribonucleic acid) is a polymer of ribonucleotides and is made up of ribonucleotides joined together by phosphodiester bonds. DNA (deoxyribonucleic acid) is a polymer of deoxyribonucleotides and is made up of deoxyribonucleotides joined together by phosphodiester bonds.

So, the correct answer is option B.
