Question:
RNA polymerase
Answer:
Enzyme that separates DNA strands and also joins together complementary RNA nucleotides
Question:
Transcription factors
Answer:
Assists RNA polymerase binding; controls rate of mRNA transcription
- / 4
Question:
Transcription initiation complex
Answer:
Combination of transcription factors, TATA box, and other proteins that allow for RNA polymerase to bind
Question:
True or False. The TATA box is necessary for initiation of transcription and is located on the RNA strand.
Answer:
false
Question:
Describe the process of elongation during transcription.
Answer:
Once unwinding of the DNA strand occurs, RNA polymerase uses the DNA strand as a template adding complementary RNA nucleotides. The synthesized mRNA pulls away from the DNA template so that the DNA strands can re-associate.
