BIO 350 Lecture Notes - Lecture 2: Non-Coding Rna, Ribosomal Rna, Uracil
Document Summary
Class q: what is the feature on a chromosome that ini(cid:2210)ates a dna replica(cid:2210)on bubble? i. Class q: what most likely explains how bacterial, archaeal, and eukaryo(cid:2210)c cells share these fundamental elements? (cid:400). C(cid:337) they most likely shared a last common ancestor ii: which way (cid:336)to the right or le(cid:91)(cid:337) are the rna polymerases moving? (cid:400). A(cid:337) to the le(cid:91) iv: gene picture click q"s: (cid:400). (cid:401). (cid:402). (cid:336)a(cid:337) to the le(cid:91) (cid:336)b(cid:337) to the right promoter (cid:336)a(cid:337) watson. Transcrip(cid:2210)on copying something from dna to rna, they are slightly di erent. Kingdom archaea and bacteria u(cid:2210)lize a single polymerase for all transcrip(cid:2210)onal needs. Pol ii: protein coding genes, small rna genes, non-coding rna genes, tes. Pol iii: (cid:404)s rrna genes, trna genes, other small rna genes. Transcrip(cid:2210)on is a selec(cid:2210)ve process - individual genes are transcribed only as their products are needed. Raw materials to build a new rna molecule. Transcrip(cid:2210)on apparatus protein needed to catalyze the synthesis of rna.
