A) having similar sugars
B) having similar pyrimidine bases
C) being capable to replicate
D) being polymers of nucleotides
Correct Answer: D
Solution :
Sol. (d)| DNA composition | RNA composition |
| Deoxiribose sugar Adenine, guanine (purine) and cytosine, thymine (pyrimidine), nitrogenous bases. Phosphate molecules. It is polymer of nucleotides. It is capable to replicate in all cases because it functions as heredity material. | Ribose sugar Adenine, guanine (purine) and uracil and cytosine (pyrimidine) nitrogenous bases. Phosphate molecules It is also polymer of nucleotides. It is formed from DNA by the process of transcription only in few causes (RNA viruses) it functions as heredity material as in viruses. |
