Q: where is RNA Polymerases l Location?
In nucleolus
Q: where is RNA Polymerases ll Location?
In nucleus
Promoters which lack a TATA box are
referred to as
TATA less promoters .
TATA box(-25) is an example of which promoter?
Class II promoters: Core promoter
pre-initiation complex contain of:
RNA polymerase II + six general transcription factors
basic unit of chromatin
nucleosome.
leads to loosing the contact between histones and DNA.
Acetylation
catalyzed leads to tight binding between histonsand DNA
De acetylation
when a polyadenylation signal appears in the RNA transcript .
Termination begins
RNA polymerase copies …… strand of DNA into RNA
One strand
RNA is always synthesized in the ……… direction
5 to 3 direction
DNA template strand in a …….. direction.
3 to 5direction.
DNA strand which has the same sequence as the RNA is called
coding or sense strand
