Immediately following the inverted methylated base 5' cap.
Followed by start codon
Non translated

Immediately after the the stop codon
Followed by Poly A tail
Non translated

2

Start and Stop Codons

AUG - Start
UAG - Stop
UAA - Stop
UGA - Stop

Holoenzyme

prokaryotic RNA poly enzyme consists of various subunits that comprise the holoenzyme

5

Core Enzyme

RNA poly subunits without Sigma subunit

Sigma Subunit

Recognizes the promoter regions

7

Rifampicin

antibiotic
used to distinguish eukaryotic RNA polymerases
