The correct answer will be- newly synthesized polypeptide
Explanation:
The process of translation or the synthesis of proteins takes place in the ribosomes which provide a site for the synthesis of polypeptides. The ribosomes are made up of two subunits: small and large subunits which provides slots namely A, P and E sites.
The tRNA brings specific amino acid corresponding to the codon of the mRNA and during elongation, the tRNA molecule moves from A site to P site to E site.
The component which exits the exit tunnel is the formed polypeptide chain which exits from the E or exit site.
Thus, the newly synthesized polypeptide is the correct answer.
