Question

Once the DNA strand is transcribed, the mRNA strand is sent out of the nucleus to ribosomes for translation. What would most likely occur at letter D, as the mRNA strand moves along the ribosome complex?
Responses
A tRNA molecules attach to the ribosome and start to degrade.tRNA molecules attach to the ribosome and start to degrade.
B tRNA molecules carrying amino acids start aligning with the mRNA codons.tRNA molecules carrying amino acids start aligning with the mRNA codons.
C tRNA molecules start the replication process inside the ribosome.tRNA molecules start the replication process inside the ribosome.
D tRNA detaches from amino acids and exits the ribosome.

Answer 1

B — tRNA molecules carrying amino acids align their anticodons with the mRNA codons at the ribosome so the amino acids can be added to the growing polypeptide chain.
