When does transcription occur?
During
protein synthesis
Where does transcription occur?
Nucleus
What are the three stages of transcription?:
Double
helix unwinds, one strand acts as a
template
mRNA
is produced
mRNA attaches to
ribosome
What happens in the first stage of transcription?
double
helix unwinds
DNA unzips / weak
hydrogen
bonds break into
two
separate strands
one strand acts as a
template
What happens during the second stage of transcription?
Free floating RNA
nucleotides
from nucleoplasm
Join to their
complementary
DNA base triplets or A-U and
G-C
This produces
mRNA
