BIOL 200 Lecture Notes - Lecture 3: 23S Ribosomal Rna, Pseudogene, Rad51
Document Summary
Beta helix: laterally packed beta strands, r-groups point outwards (cid:120) beta-strand = short, 5-8 residues, nearly extended polypeptide segment (cid:120) h-bonding between backbone of beta strands. Directionality parallel (same orientation) or antiparallel (opposite orientation) Supramolecular structure (cid:120) macromolecular assemblies (cid:120) usually >1 megadaltons in size (cid:120) (cid:1005)(cid:1004)(cid:859)s to (cid:1005)(cid:1004)(cid:1004)(cid:859)s of pol(cid:455)peptide (cid:272)hai(cid:374)s (cid:894)as (cid:449)ell as othe(cid:396) (cid:373)a(cid:272)(cid:396)o(cid:373)ole(cid:272)ules(cid:895) Fibrous proteins ca2+ binding proteins rna and dna binding proteins. Lecture 4 flow of info: transcription and translation. The ingredients needed for transcription in bacteria (rna polymerization) (cid:120) dna template: to serve as blueprint for the rna sequence (cid:120) ribonucleotides: to serve as monomers for rna polymerization (rntps) (cid:120) rna polymerase: to catalyze the synthesis of rna. Nontemplate strand (cid:198) sense: because it looks very similar to the primary transcript, product of transcription. Template strand (cid:198) antisense: it is the exact complement of the sense strand.
