What happens to the tRNA after it delivers amino acids to the ribosome during translation?
A
It is converted into mRNA.
B
It is degraded by the ribosome.
C
It is released from the ribosome and can be reused.
D
It becomes part of the ribosomal structure.
Verified step by step guidance1
Understand the role of tRNA in translation: tRNA molecules are responsible for bringing amino acids to the ribosome, where proteins are synthesized.
Recognize the process of translation: During translation, the ribosome reads the mRNA sequence and uses tRNA to add the correct amino acids to the growing polypeptide chain.
Identify what happens after tRNA delivers its amino acid: Once the tRNA has delivered its amino acid to the ribosome, it is no longer needed for that particular amino acid addition.
Determine the fate of tRNA post-delivery: After delivering the amino acid, the tRNA is released from the ribosome.
Understand the reusability of tRNA: The released tRNA can be recharged with a new amino acid and reused in subsequent rounds of translation, making it an efficient component of protein synthesis.
