Multiple Choice
In translation, which RNA molecule carries specific amino acids to the ribosome by matching its anticodon to an mRNA codon?
A
tRNA (transfer RNA)
B
mRNA (messenger RNA)
C
rRNA (ribosomal RNA)
D
snRNA (small nuclear RNA)
Verified step by step guidance1
Understand the process of translation, which is the synthesis of proteins from mRNA templates in the ribosome.
Recall that mRNA (messenger RNA) carries the genetic code from DNA in the form of codons, which are sequences of three nucleotides.
Identify that tRNA (transfer RNA) molecules are responsible for bringing specific amino acids to the ribosome during translation.
Recognize that each tRNA has an anticodon region that is complementary to the mRNA codon, allowing it to match the correct amino acid to the growing polypeptide chain.
Note that rRNA (ribosomal RNA) forms the core of the ribosome's structure and catalyzes peptide bond formation, while snRNA (small nuclear RNA) is involved in RNA splicing, not translation.
