Q. No.Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
In the light of the above statements, choose the most appropriate answer from the options given below :
| Assertion (A): | An adapter molecule, that on one hand can read the genetic code and on the other hand can bind to specific amino acids, is required for the translation of proteins. |
| Reason (R): | Amino acids have no structural specialties to read the code uniquely. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are False. |
| 3. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 4. | (A) is True but (R) is False. |
