promoter sequence tells where polymerase to start - upstream of the gene (5 prime direction)

rna builds 5'3 like DNA and it reads 3'5

terminator sequences tells where polymerase to end/get off

coding strand - doesn't code but its genetic code is the perfect match for the mrna strand except it is U instead of T.

RNA polymerase vs DNA polymerase

• rna doesn't proofread
• rna doesn't need a primer doesn't / need DNA primase / transcription can happen quickly and rapidly - all it needs is the enzyme to find its primer and starts copying the strand

during transcription:

• the eukaryotic cells introns never become transcribed / they are turned to rna transcript where splicing takes place, only keeping the exons; exons are the ones that make protein
• WE KEEP EXONS AND TAKE OUT INTRONS !!!

the cap is used for stability and to send the mRNA out
