MCQ
Purines and pyrimidines polymerise to form:
- ANucleoside
- BNucleic acid
- CRibonucleotides
- DAll of the above
Explanation:
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.
