Question

One of the similarities between DNA and RNA is that both

(a) are polymers of nucleotides

(b) are capable of replicating

(c) have similar sugars

(d) have similar Pyrimidine bases

Answer 1

Correct option (a)**Are polymers of nucleotides**

Explanation :

| DNA Composition | RNA Composition |
| Deoxyribose sugar. | Ribose sugar |
| Adenine, guanine (both purine) and cytosine, thymine (both pyrimidine),nitrogenous bases. | Adenine,guanine (both purine) and uracil, cytosine (both pyrimidine) nitrogenous bases. |
| Phosphate molecules. | Phosphate molecules. |
| It is polymer of nucleotieds. | It is also polymer of nucleotides. |
| It is capable to replicate in all cases because it functions as heredity material. | It is formed from DNA by the process of transcription only in few cases (RNA viruses) rt functions as heredity material. |
