An elongating ribosome is bound to appropriate tRNAs in both the A and P sites and is ready for peptidyl transfer. What happens
next? (A) The carboxyl end of the polypeptide chain is released from the P-site tRNA and joined to the free amino group of the amino acid linked to the A-site tRNA.
(B) The carboxyl end of the amino acid is released from the A-site tRNA and joined to the free amino group of the polypeptide chain linked to the P-site tRNA.
(C) The tRNA with the growing peptide chain is translocated to the E-site where the amino acid from the A-site tRNA will be linked to the polypeptide chian.
(D) The tRNA with the amino acid attached is translocated to the E-site before it is linked to the growing polypeptide chain.
The ocean acidification is generally caused by the vast amounts of carbon dioxide that humans release in the air gettting absorbed into the ground, causing the PH of the water to rise. Hopefully this helps!
