What is an example of RNA editing? Changing a valine codon to a stop codon Methylation of cytosine bases Formation of RISC Alternative splicing

Enhancers and silencers increase or decrease transcription levels from the distance bind to the RNA polymerase are essential for chain elongation are essential for termination

What is substitution RNA editing ?

Why is RNA editing important?

One fundamental difference between transcription in prokaryotes and eukaryotes is: eukaryotic RNA transcripts undergo polyadenylation (poly-A tail; cap) eukaryotes produce single RNA transcripts called operons that code for several proteins prokaryotes undergo capping of their 5' end of the RNA transcript prokayotic transcription occurs in the nucleus O prokaryotes have intervening sequences that are spliced during processing of the RNA transcript

Describe the initiation step of bacterial transcription (make sure to include important enzymes, parts, and sequences in your answer) up to the beginning of elongation. What are three ways that transcription differs between bacteria and eukaryotes? (I'm not looking for types of RNA modification, just in terms of transcription)

During the transcription elongation step, an internal structure in the RNA Polymerase called _______________________ helps unwind the newly made RNA from the template DNA strand, allowing the RNA to exit through a rear channel on the RNA polymerase.     flap sigma rudder zipper alpha

Which of the following sequences would most likely be the site of the initiation of transcription? ТАТАААТА GCTAGCTA GGCGGCCC Impossible to tell

In eukaryotic transcription, which of the following is not included in the initiation of transcription? Group of answer choices RNA polymerase II TATA box Holoenzyme AAUAAA consensus sequence
