Which of the following is a function of a tRNA molecule?
A
To carry amino acids to the ribosome during protein synthesis
B
To catalyze the formation of peptide bonds
C
To serve as a template for mRNA synthesis
D
To form the structural components of ribosomes
Verified step by step guidance1
Understand the role of tRNA in protein synthesis: tRNA, or transfer RNA, is responsible for bringing amino acids to the ribosome, where proteins are synthesized.
Recognize the structure of tRNA: tRNA molecules have a specific three-dimensional structure that allows them to carry specific amino acids and match them with the corresponding codons on the mRNA strand.
Identify the anticodon region: Each tRNA molecule has an anticodon region that is complementary to a codon on the mRNA. This ensures that the correct amino acid is added to the growing polypeptide chain.
Differentiate between the functions of different RNA types: mRNA serves as the template for protein synthesis, rRNA forms the core of ribosome's structure and catalyzes protein synthesis, while tRNA carries amino acids to the ribosome.
Conclude the function of tRNA: Based on the understanding of its role and structure, the primary function of tRNA is to carry amino acids to the ribosome during protein synthesis.
