Why is mRNA called "messenger" RNA?

Question

a
It looks like letters with a "message" under the microscope.
b
It carries codes for proteins from DNA into the cytoplasm to be used in protein synthesis.
c
It acts as a virus, carrying the message of cellular control.
d
It carries codes for proteins from the cytoplasm to the DNA for DNA synthesis.

Answer 1

The correct answer is:

b. It carries codes for proteins from DNA into the cytoplasm to be used in protein synthesis.

mRNA (messenger RNA) is called "messenger" RNA because it serves as the intermediary that carries genetic information from DNA in the nucleus to the ribosomes in the cytoplasm, where proteins are synthesized.
