Unformatted text preview: Biol142 Foundations in Modern Biology II Cellular Biology and Genetics Lecture 21 Monday, March 19 th , 2012 Eukaryotic Gene Regulation III Reading: Freeman, Emory 2 nd Ed. Chapter 18 (pages 328 - 332) Learning objectives At the end of this lecture, you will be able to: 1) Describe the role of RNA interference (RNAi) in the degradation of cytoplasmic mRNA. 2) Explain the role of regulating the rate or timing of translation upon the activity of a protein. 3) Describe the process of ubiquitination in regulating the lifespan of a protein. Overview of gene regulation : Eukaryotic gene expression can be regulated at 3 steps within the nucleus. Alternative splicing allows a single gene to code for several different products. Step # 1 Step # 2 Step # 3 Chromatin remodeling : Transcriptional regulation: DNA is packaged with proteins into complex structures that must be opened for transcription to occur....
