PPT-Gene Expression and Cell Differentiation

CSCOPE Unit 08 Lesson 01 There are hundreds of different types of cells in your body and each type has a unique function Were going to compare some different types of cells to see how much they have in common . Inducible gene expression. kinetics of . β-galactosidase. enzyme induction. Add inducer. start transcription = mRNA accumulation. mRNA translation = protein accumulation. Remove inducer.

Cancer is a multistep process in which cells grow and divide abnormally, disrupting physical and metabolic functions. More . than 200,000 new cases of breast cancer are diagnosed in the US each year – about 5,700 in women and men . Draw 8 boxes on your paper. Gene regulation accounts for some of the phenotypic differences between organisms with similar genes.. 2005-2006. Gene regulation in bacteria. Control of gene expression enables individual bacteria to adjust their metabolism to environmental change. RNA can destabilize mRNA. Single-stranded RNA can affect gene expression. Double-stranded RNA can affect gene expression. All of above. . Before their study, it is known that. Single stranded RNA can cause RNA interference. Controlling gene expression is often accomplished by controlling transcription initiation..
