____ Carries Protein Assembly Instructions from the Nucleus to the Cytoplasm

Question

____ carries protein assembly instructions from the nucleus to the cytoplasm.  
A) Template DNA
B) Messenger RNA
C) Transfer RNA
D) Ribosomal RNA
E) Total RNA

Accepted Answer

Messenger RNA (mRNA) carries genetic instructions from DNA in the nucleus to ribosomes in the cytoplasm, which in turn synthesize proteins based on the instructions carried by the mRNA. The other types of RNA listed (template DNA, transfer RNA, ribosomal RNA, and total RNA) also play important roles in protein synthesis, but only mRNA carries the specific instructions for assembling a particular protein.
