Question

Quizplus · Accepted Answer

mRNA (messenger RNA) is synthesized from a DNA sequence during transcription, and it carries the message from the DNA to the ribosome for translation. It is the molecule that must move across the membrane to reach the ribosome. DNA, rRNA (ribosomal RNA), and tRNA (transfer RNA) do not need to move across the membrane as they are already present within the cell.
