BIO 161 Chapter Notes - Chapter 7: Euchromatin, Post-Translational Modification, P53
Document Summary
Reading: chapter 18, chapter 19, chapter 16 (pg 313-315), chapter 15, pg 297-302. Objectives: understand the experiment shown in figure 18. 2 and explain why results are consistent with the idea that gene expression is a regulated process, the lac operon will be covered in lecture and lab. It is very important that you can explain how the lac operon allows control of the expression of lactose metabolic genes. You must understand the roles of the all of the following components: Lac z gene ( -galactosidase), rna polymerase, promoter, operator, repressor (lac i), lactose, glucose: how could mutations to the components mentioned above alter the expression of lac. How? (chromatin, heterochromatin, euchromatin, histones, acetylation, methylation: list some of the major differences between prokaryotic and eukaryotic gene expression, review the role of p53 in regulation of the cell cycle.
