Which one of the following is true of tRNAs?
A
tRNAs serve as templates for mRNA synthesis.
B
tRNAs are involved in DNA replication.
C
tRNAs are the main component of ribosomes.
D
tRNAs carry amino acids to the ribosome during protein synthesis.
Verified step by step guidance1
Understand the role of tRNA in the cell: tRNA (transfer RNA) is a type of RNA molecule that plays a crucial role in protein synthesis by carrying amino acids to the ribosome.
Eliminate incorrect options: tRNAs do not serve as templates for mRNA synthesis. This process is carried out by DNA during transcription.
Eliminate another incorrect option: tRNAs are not involved in DNA replication. DNA replication involves enzymes like DNA polymerase and other factors, not tRNA.
Eliminate the third incorrect option: tRNAs are not the main component of ribosomes. Ribosomes are primarily composed of rRNA (ribosomal RNA) and proteins.
Confirm the correct answer: tRNAs carry amino acids to the ribosome during protein synthesis, where they match their anticodon to the mRNA codon to ensure the correct sequence of amino acids in the growing polypeptide chain.
