Q.

Which of the following processes take place outside the nucleus?

1. Protein synthesis

2. Replication

3. Transcription

4. None of the above

Q. Regarding the assertion and reason, select the correct choice.
Assertion [A]: The amino acid-bound tRNA enters the aminoacyl tRNA binding site.
Reason [R]: The amino acid-bound tRNA transfers the amino acid at the peptidyl tRNA site.

1. Both A and R are true and R explains A
2. Both A and R are true, but R does not explain A
3. A is true and R is false
4. Both A and R are false
