Question

the model shows trna.
what is the function of trna in the cell?
○ to check the polypeptide for errors after translation is complete
○ to make up half the composition of the ribosome along with proteins
○ to supply the correct amino acid to the ribosome for translation
○ to transmit the genetic code from the nucleus to the ribosome

Explanation:

Transfer RNA (tRNA) is a type of RNA molecule that carries a specific amino acid to the ribosome during translation. It matches its anticodon sequence to the codon on mRNA, ensuring the correct amino acid is added to the growing polypeptide chain. The other options are incorrect: checking polypeptide errors is not its role, it does not form part of the ribosome, and transmitting genetic code from nucleus to ribosome is the function of mRNA.

Answer:

○ to supply the correct amino acid to the ribosome for translation
