Which of the following statements is true of mRNA?
A) It contains 73-93 nucleotides per chain.

C) It is a long-lived molecule.
D) Its nucleotide sequence is complementary to that of a DNA strand being transcribed.

Question

Quizplus · Accepted Answer

mRNA is synthesized in the nucleus by RNA polymerase during a process called transcription. During this process, the mRNA molecule is synthesized from a DNA template and its nucleotide sequence is complementary to that of the transcribed DNA strand. Additionally, mRNA molecules are relatively short-lived and degraded quickly in the cytoplasm once they have served their purpose in protein synthesis. The length of an mRNA molecule can vary widely, typically ranging from a few hundred to a few thousand nucleotides per chain.
