Why is mRNA called "messenger" RNA?
a
It carries codes for proteins from the cytoplasm to the DNA for DNA synthesis.
b
It acts as a virus, carrying the message of cellular control.
c
It looks like letters with a "message" under the microscope.
d
It carries codes for proteins from DNA into the cytoplasm to be used in protein synthesis.
d
It carries codes for proteins from DNA into the cytoplasm to be used in protein synthesis.
Messenger RNA (mRNA) is so named because it serves as a template to convey genetic information from DNA to the ribosomes, where proteins are synthesized according to this "message." This process of protein synthesis is also called translation. The mRNA is first transcribed from the DNA in the nucleus and then it travels into the cytoplasm where ribosomes read the encoded message to build the corresponding protein.
