pack 9 Flashcards
What is the promoter?
DNA sequence that acts as a transcription start site.
(it is promoting (advertising) transcription) (it promotes the transcription to the rna polymerase to convice it to start transcription)
What is the job of terminators?
It is the site where transcription stops.
What type of RNA polymerase genes is used to transcribe most genes?
RNA polymerase 2
What is the anti sense strand?
The template strand, the strand that is anti to the transcipted rna strand.
What is the coding/Sense strand?
It is the strand that isnt used for the template, it is called coding bc it has almost the same code as the RNA strand and also has the same sense.
What is the base number?
It is: Numbering system used to identify important bases.
+1:The first base transcribed as RNA
+2, +3, … : anything to the right of the +1 (to the 3’) (downstream)
-1, -2, -3, …. : anything to the left of the +1 (to the 5’) (up stream)
What are the different eukaryotic promoter elements?
CAAT box
TATA box
Cap site
GC box
Does RNA proofread its work?
NO
What does (α-amanitin) do?
Function:it inhibits polymerase II causing cell death
Found in: Certain mushrooms
(you think that the mushrooms is amina but it actually isn’t)
What are introns?
Spacer DNA that don’t code for anything
