Bio 97 (#61860): Lecture 13 Class Notes 10/3/2016 (Powerpoint slides “Bacterial Genetics I”) I. Bacterial Clones A. once you spread cells out -> get visible colonies B. colonies result of division C. replicate by binary ﬁssion D. genetic clones of one another II. Mutations in Bacteria A. carbon source mutant - inability to grow when particular sugar is sole sugar or carbon source on medium B. sugars 1. carbons, hydrogens, and oxygens in 1:2:1 ratio a) these are usually sugars 2. polysaccharides need to get broken down into simple sugars 3. needs extra membrane proteins to get into cell 4. cell needs to make extra proteins to utilize these carbohydrate sources C. media 1. MM = glucose
