Which type of RNA contains an anticodon region that pairs with codons on mRNA during translation?
A
tRNA (transfer RNA)
B
rRNA (ribosomal RNA)
C
mRNA (messenger RNA)
D
snRNA (small nuclear RNA)
Verified step by step guidance1
Understand the role of RNA in protein synthesis: RNA molecules play different roles in the process of translation, which is the synthesis of proteins based on the sequence of codons in mRNA.
Learn about codons and anticodons: Codons are three-nucleotide sequences on mRNA that specify amino acids, while anticodons are complementary three-nucleotide sequences on another type of RNA that pair with codons during translation.
Identify the type of RNA with anticodons: Transfer RNA (tRNA) contains the anticodon region. This region is responsible for recognizing and binding to the complementary codon on the mRNA strand during translation.
Understand the function of tRNA: tRNA carries specific amino acids to the ribosome, where the anticodon pairs with the codon on mRNA, ensuring the correct amino acid is added to the growing polypeptide chain.
Differentiate tRNA from other types of RNA: rRNA (ribosomal RNA) forms the structure of ribosomes, mRNA (messenger RNA) carries the genetic code from DNA, and snRNA (small nuclear RNA) is involved in RNA processing, but none of these contain anticodons.
