Transcription Flashcards
where does transcription occur?
the nucleus
where does translation occur?
cytoplasm or RER
where does RNA processing occur?
the nucleus
gene definition
the stretch of DNA that is transcribed into RNA also called transcription
what are the main stages of transcription
initiation, elongation, termination
what is the promoter region?
where the RNAP first binds and RNAP starts transcribing and has the transcription start point
how many promoters do prokaryotes have?
one RNAP
how many promoters do eukaryotes have? Name them and what do they do
3:
RNAP I makes rRNA
RNAP II involves in transcription (makes mRNA)
RNAP III makes tRNA
Where is the promoter located?
upstream ofthe gene
what is the promoter composed of?
an AT rich region
why is the promoter composed of AT rich region
AT have fewer hydrogen bonds, meaning they require less energy to have
