Question

question 3 of 6
during the elongation phase of translation within a ribosome, to which site does an incoming trna molecule carrying the next amino acid initially bind?
the a (amino acid) site.
the p (polypeptide) site.
the e (exit) site.

Explanation:

In the elongation phase of translation in a ribosome, the incoming t - RNA molecule carrying the next amino acid initially binds to the A (amino - acid) site. The P (polypeptide) site holds the t - RNA with the growing polypeptide chain, and the E (exit) site is where the t - RNA exits after it has released its amino acid.

Answer:

The A (amino acid) site.
