In eukaryotes, TRANSCRIPTION FACTORS:
|
Mediate the binding of RNA polymerase and the initiation of transcription.
|
|
|
Transcription Initiation Complex:
|
The complete assembly of transcription factors and RNA polymerase bound to a promoter.
|
|
|
Eukaryote promoter includes?
|
TATA box, Start point.
It is followed by a template DNA strand. Several transcription factors (proteins) bind to the DNA before RNA polymerase can do so. Additional transcription factors bind to the DNA along w/ RNA polymerase forming the transcription initiation complex. |

they do not do it

|
Spliceosome / snRNPs
|
= variety of proteins and several small nuclear ribonucleoproteins (snRNPs) that recognize the splice sites; the spliceocome contains the catalyst that promotes splicing.
|
|
|
ribozyme
|
catalytic RNA molecule - catalyzes the splicing of mRNA molecule
