The tRNA nucleotide sequence that lines up on the mRNA is
A)an intron.
B)an exon.
C)a release factor.
D)an initiation factor.
E)an anticodon.

Question

Quizplus · Accepted Answer

The tRNA nucleotide sequence that lines up on the mRNA is called an anticodon. This is the region of the tRNA that is complementary to the codon on the mRNA, allowing for proper base pairing and the insertion of the correct amino acid into the growing polypeptide chain. Options A and B are incorrect because introns and exons are regions of DNA and not involved in the tRNA-mRNA interaction. Options C and D are incorrect because release factors and initiation factors are proteins involved in translation, but not directly involved in the tRNA-mRNA interaction.
