Answer is prokaryotes
Because it is part of eukaryotic transcription . It contains Enhancer and Activators and transcription factors and RNA polymerase II
An enhancer is NOT associated with: Prokaryotes Transcription RNA Polymerase II Transcription activator
4. A protein that works with RNA polymerase in prokaryotes to initiate transcription (two words, no spaces). 5. Prokaryotic transcription and translation are events. 7. The DNA used as a template molecule during transcription is an molecule. 8. The leading strand of DNA is synthesized 9. The sequence of DNA found 35 base pairs upstream from the start of a gene in prokaryotes
#1 Match the protein to it's function in transcription: RNA polymerase III, Transcription Factor IID, Transcription Factor IIE, Sigma Factor, Transcription Factor IIH, RNA polymerase II, Helicase, RNA polymerase II •Transcribes tRNA •Recognizes promoter region in bacteria •Transcribes mRNA •Recognizes promoter region in eukaryote •Exposes a single stranded DNA template

Describe in detail the structure of the RNA polymerase II CDT and how the structure is used to sequentially regulate the maturation of the pre-mRNA during the elongation phase of transcription. Focus on the events which happen on RNA polymerase II CDT. For mechanisms which are directly responsible for pre-mRNA processing, you only need to mention their names.
Transcription regulators control transcription by phosphorylating RNA polymerase. binding to specific sequences of DNA. binding to specific sequences of RNA. degrading mRNAs.
Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of molecule "C", protein "A" changes structure and can no longer bind to the DNA sequence, resulting in reduced transcription of CBC23. What terms describe "A" and "C" respectively? Enhancer and activator Repressor and Effector Effector and activator Activator and enhancer Polymerase and activator Activator and effector
