Question

What stimulates the ribosome to move down one codon?

A stop codon entering the A site

The hydrolysis of ATP

A new tRNA entering the A site

The formation of a bond between the peptide in the P site and the amino acid in the A site

The release of a tRNA from the E site

If an aminoacyl-tRNA synthetase added the wrong amino acid to a tRNA, what would happen?

The tRNA would associate with the wrong codon, and the wrong amino acid would be incorporate into the growing peptide.

The ribosome would not be able to recognize the start codon, and translation would not eb initiated.

The tRNA could not bind to the ribosome, and no amino acid would be added to the growing peptide The tRNA would carry the wrong amino acid, and it would be incorporated into the growing protein

The ribosome would not be able to recognize the stop codon, and translation would continue to occur when it should have been terminated

Explanation / Answer

1. The answer is: The formation of a bond between the peptide in the P site and the amino acid in the A site.

The formation of a bond between the peptide in the P site and the amino acid in the A site stimulates the ribosome to move down one codon.

2. The answer is:  The tRNA would carry the wrong amino acid, and it would be incorporated into the growing protein.

If an aminoacyl-tRNA synthetase added the wrong amino acid to a tRNA, the tRNA would carry the wrong amino acid, and it would be incorporated into the growing protein.
