Description: Which one is the next tRNA that will arrive to the "A" site of this ribosome?GlyPreviousArgGluProValOCysUAGGMetProUAGG

The A site is where the next tRNA molecule carrying an amino acid binds to the mRNA. The tRNA molecule is selected based on the codon currently at the A site of the ribosome. Each tRNA molecule carries a specific amino acid and has an anticodon that pairs with the codon on the mRNA.Answer:Given the mRNA sequence AUG CCA GGC, the corresponding amino acids would be Methionine (Met), Proline (Pro), and Glycine (Gly).If Met and Pro are already in the P and E sites of the ribosome, the next tRNA molecule to arrive at the A site would be the one carrying Glycine (Gly), as it corresponds to the next codon (GGC) in the mRNA sequence.The rest of the options are not possible from the GGC codon.In summary, in the context of the given mRNA sequence (AUG CCA GGC) and the current state of the ribosome (with Met and Pro already in the P and E sites), the next tRNA molecule to arrive at the A site of the ribosome would be the one carrying Glycine (Gly). This is because Glycine corresponds to the next codon (GGC) in the mRNA sequence.
