What is the process of making an RNA copy of a gene?
replication
transcription
translation
nucleosomes
Where does transcription take place in a cell?
always in the nucleus
always in the cytoplasm
in the nucleus in eukaryotes and the cytoplasm in prokaryotes
in the cytoplasm in eukaryotes and the nucleus in prokaryotes
What enzyme is responsible for transcription?
DNA polymerase
RNA polymerase
ribosomes
nucleolus in the nucleus
Following transcription in eukaryotes, the RNA
stays in the nucleus
is made into mRNA and goes to the cytoplasm
goes directly to the cytoplasm without changes
goes back to the nucleus for changes
