a.  In eukaryotic cells, what must happen before transcription can begin?

b.  What does an activator do to increase the level of transcription of a gene in a eukaryotic cell?

The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.
Learn more on how we answer questions.

a.  A series of transcription factors must bind to the promoter region before RNA polymerase can bind to the DNA to initiate the transcription process.
b.  An activator makes it easier for RNA polymerase to bind to the promoter region of eukaryotic DNA, thus increasing the level of transcription of a particular gene.
