In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...

Except for the molecule carrying the very first amino acid, all enter this organelle at the site. The movement of the ribosome with respect to the mRNA is (translation/ translocation), and it occurs each time a known as new amino acid is added to the polypeptide chain, in other words, during the cycle of the ribosome.
