Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
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.
In the light of the above statements, choose the most appropriate answer from the options given below :
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.

Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): In the first phase of translation, it is important that the charging of tRNA in the presence of ATP takes place.
Reason (R): The formation of a peptide bond requires energy.
In the light of the above statements, choose the most appropriate answer from the options given below :
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are False.
