Question -
Identify the molecule in the following image:
Options:
A .  Ribonucleic acid
B .  Deoxyribonucleic acid
C .  Ribonucleotide
D .  Deoxyribonucleotide
Answer: Option A : A The given structure shows a few nucleotides bonded together to form a long chain, which indicates that the molecule is a nucleic acid and not an individual nucleotide. The sugar molecule in the given structure is ribose, and hence, the molecule has to be ribonucleic acid. Moreover, there is a molecule of uracil shown as part of this polymer, which too, gives a hint that it is RNA and not DNA.
