Document Summary

Transciption will use one of the dna strands whereas in dna replcationi both strands are used. In rna transcription we use the antisense strand , because rna polymerase only adds strands o(cid:374) the (cid:1007)" e(cid:374)d. The se(cid:374)se st(cid:396)a(cid:374)d (cid:1007)" e(cid:374)d (cid:449)ill o(cid:374)l(cid:455) (cid:271)e a(cid:448)aila(cid:271)le fo(cid:396) elo(cid:374)gatio(cid:374) Thus transciption generally goes in theoppposite direction. Translation and transcription are in separate compartments. Eukaryotes are composed of different rna polymerase. Prokaryotes only have 1: alpha subunit responsible for. Binding to activatos: b, b", sigma promoter specificity (protomotor specificity) Note: translation and tranciption of genes do not occur randomly. Eukaryote rna polymerase (we have an entire lecture on this) Rrna5s is not find in the cell. Note with these two pictures: notice that prokaryotic rna polymerase is very similar to eukaryotic rna polymerase, they catalylse the same biochemical reactions. Some antibitics can distinction between prokaryotic and eukaryotic. Rifampicin can bind to the prokaryote rnapolymerase and will not bind to the eukaryote rna polymerase.
