During Protein synthesis, what does mRNA do?
it delivers DNA's instructions for making proteins to the ribosomes
it constructs protiens out of amino acids
it strings together two complementary RNA strands
It delivers amino acids to assemble the polypeptide
Where does TRANSCRIPTION occur?
Nucleus
Ribosome
Cytoplasm
Mitochondria
Why must transcription occur where DNA can be found?
because DNA can't leave
because ribosomes are in the nucleus
because DNA polymerase is found there
because helicase unzips the DNA
