The bottom strand The top strand Whichever strand permits synthesis in the 5' to 3' direction Both strands

Answer 1

$\bullet$ The correct answer is rRNA within the large ribosomal subunit catalyzes the reaction.

Explanation: The enzyme responsible for the formation of a new peptide bond during the translation process is called peptidyl transferase. It is present in the large ribosomal subunit. This enzymatic activity is carried out by the ribosomal RNA (ribozyme i.e. RNA molecule with the catalytic activity). This results in the addition of an amino acid to the growing peptide chain.

$\bullet$Question 26: The correct answer is Whichever strand permits synthesis in the 5' to 3' direction.

Explanation: Promoter region can be defined as the DNA sequence where the RNA Polymerase binds to initiate the transcription process using one of the DNA strands as a template. The template strand is always read in the 3' to 5' direction so that the RNA Polymerase synthesizes the RNA in 5' to 3' direction.
