Document Summary

It has specific sites called -35 and -10 sequence. Rna polymerase recognizes the site as the start of transcription. Promoter is not transcribed (never appears in the mrna) Start point of transcription is +1 (not atg: atg is the start sequence written in the dna in the 5" to 3". 3" to 5" template strand is tac. 5"utr starts after the promoter (after the start point +1) Shine dalgarno sequence (sd box) is a sequence that is coded in the dna but interpreted and recognized by the cell as rna. Ribosome recognizes this site and binds to it, and then know that now it has t logo look for atg in order to start transcription. Ribosomes recognizes the sd box though complimentary base pairings. Ribosomes are made up of proteins and rna sequence. Rna part recognizes the sd box and complimentary base pairs with it. How is transcription terminated: rho dependent and rho independent.
