After forming a complex with the ribosome, mRNA interacts with a third molecule.This molecule is called
A) DNA.
B) an amino acid.
C) rRNA.
D) tRNA.
E) rough ER.

Question

Quizplus · Accepted Answer

After forming a complex with the ribosome, mRNA interacts with tRNA, which brings in the amino acids and helps in the synthesis of the protein. Choice A (DNA) is not correct because mRNA does not interact with DNA after leaving the nucleus. Choice B (an amino acid) is not correct because mRNA does not directly interact with amino acids. Choice C (rRNA) is a component of the ribosome and helps in the protein synthesis process but is not the molecule that interacts with mRNA after ribosome binding. Choice E (rough ER) is a cellular organelle involved in protein synthesis but is not the molecule that interacts with mRNA after ribosome binding.
