Document Summary

Week 6 : monday, june 10th & wednesday, june 12th 2013. The posted biology 1a03 avenue lecture outlines are not detailed lecture notes. Students are expected to supplement the posted avenue lecture outlines with their own written notes. Since supplementary lecture topics and examples will be discussed exclusively in lectures (they are not found in the textbook), it is very important that students attend all biology 1a03 lectures. Note that chapter 2 in the biology 1a03 textbook is considered assumed knowledge that should have been previously obtained in high school biology 12u. Chapter 17 control of gene expression in bacteria. Recall the steps of information flow from dna to proteins. Dna mrna protein activated protein. 17. 1 gene expression can be regulated at three levels. 17. 2 glucose affects the regulation of the b-galactosidase gene. Experiments supported that the presence of lactose, without glucose, stimulates the gene expression of the gene for beta-galactosidase.
