Document Summary

Information transfer: gene expression, to understand information transfer via gene expression, structure of dna, gene structure sub-processes, transcription, translation, control/modification mechanisms, dna is not doing this directly! 2: the central dogma, gene encodes specific protein. 3: gene transcription, rna sequence is the same as that of the coding strand of dna except that u replaces t, (cid:373)rna is (cid:271)uilt i(cid:374) a 5"-3" dire(cid:272)tio(cid:374), (cid:271)(cid:455) readi(cid:374)g the te(cid:373)plate stra(cid:374)d i(cid:374) a 3" -5". If you want to make copy: separate strand and make copy by reading 3 prime to. 5: transcription produces genetic messages in the form of rna, euk have promotor sequence: where it starts. Rna polymerase binds to sequences and moves along dna sequences and synthesize an rna strand: pro: 1 type of rna polymerase euk has 3 different types of rna polymerase. Rna polymerase ii: produces messenger rna molecules (what we are interested in right now: transcription initiation:
