Document Summary
Bio151 lecture 12 applications to transcription. A sit is where trna binds to mrna; a peptide bond is formed there. E site is where the now empty trna leaves. Wobble base pairing a term used to describe that the third nucleotide in the codon sequence can be different but still produce the same protein. Prokaryotic: no nucleus o transcriptional translation, there are no intron polycistronic dna. A must leave the nucleus: mrna processing. The gene model above is for a eukaryotic protein. Blue sections are exons and brown are introns. If you wished to make this protein in the popular lab bacterium e. coli. Pick as many numbers as you think are necessary. polyribosomes: treat the mrna with reverse transcriptase (rna dna) and insert that in the bacterial genome, add a bacterial promoter and 3"utr. A transcriptional error means that mrna will have a mutation, Mutations can be good, bad, or indifferent. It can be somatic or on the germ-line.
