Question

Consider the following and choose the correct answer Assertion [A]: Peptide bond formation occurs at the P site of the ribosome. Reason [R]: Peptidyl transferase activity is an intrinsic property of rRNA. The correct answer is

• A. Both [A] and [R] are true and [R] is the correct explanation of [A]
• B. Both [A] and [R] are true and [R] is not the correct explanation of [A]
• C. [A] is true, but [R] is false
• D. [A] is false, but [R] is true

Hint:

Ribosomal sites: \[ \boxed{ \begin{aligned} \text{A site} &\rightarrow \text{Entry of aminoacyl-tRNA} \text{P site} &\rightarrow \text{Holds peptidyl-tRNA} \text{E site} &\rightarrow \text{Exit of deacylated tRNA} \end{aligned} } \] Peptidyl transferase activity is an intrinsic property of \[ \boxed{\text{rRNA (Ribozyme).}} \]

Answer 1

The Correct Option is D
