As each codon binds at the active site of a ribosome, it interacts with another molecule. This molecule is called
A) DNA.
B) mRNA.
C) ribosomal RNA.
D) tRNA.
E) rough ER.

Question

Quizplus · Accepted Answer

The molecule that interacts with each codon at the active site of a ribosome is transfer RNA (tRNA). tRNA carries a specific amino acid that is complementary to the codon on the mRNA, allowing for the correct amino acid to be added to the growing polypeptide chain. DNA and mRNA are involved in the transcription phase of protein synthesis, while ribosomal RNA makes up the structure of the ribosome. Rough ER is not directly involved in the process of translation.
