Which step occurs in the p site of the ribosome during translation? none of the other answer options is correct. an uncharged trna is ejected from this site as the ribosome slides to the next codon. an incoming charged trna binds to this site. the trna carrying the growing polypeptide moves to this site as the ribosome slides to the next codon.

Option (4).

Explanation:

Translation may be defined as the process of formation of the protein product by the RNA molecules. Different enzymes, proteins and ribosome is required for the process of translation.

P- site ( peptidyl transferase site )is the site in which the first amino acid incorporates. Later, the next amino acid from the A site moves to the P site and the growing polypeptide moves to the P site as the ribosome moves slides to the next codon.

Thus, the correct answer is option (4).

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
