Prior steps for creating recombinant plasmids are described in traditional cloning basics and involve insertion of a DNA sequence of interest into a vector backbone. Only a fraction (less than 1 in 1000) will acquire the plasmid. • We can grow the bacteria on a plate: • That contains ampicillin and X-Gal • Regular bacterial medium • What do you predict will happen in each? creating a recombinant plasmid. Get powerful tools for managing your contents. Presentation Summary : In a typical transformation, billions of bacteria are treated and exposed to plasmid DNA. many organisms can fluoresce. • A “lawn” is too many colonies to count - plasmid + plasmid. In genetic engineering, plasmids are one means used to introduce foreign genes into a bacterial cell. 2.

Lab 9: Bacterial Transformation & Spectrophotometry, Part 1 Activity 9a Bacterial Transformation, Part 1 Purpose and Background In this lab, you will perform a procedure known as genetic transformation. Natural transformation is a bacterial adaptation for DNA transfer that depends on the expression of numerous bacterial genes whose products appear to be responsible for this process. Transformation has 4 main steps • Prepare cells • Make them competent • Incubate with plasmid • Plasmid associates with membrane of cells • Shock the cells • To initiate plasmid uptake • Allow cells to recover and plate on agar • Allow cells to recover in rich medium for 0.5 – 1 h (without antibiotic to avoid stressing the cells) • Plate on agar with antibiotic for selection • Next day can pick single colonies or clones, The Transformation Lab… • Our plasmid: pBlu plasmid • Into E. coli (scary?…no!) pglo plasmid. I • If this gene is taken in, the organism can break down lactose. Conjugation (bacterial “sex”) involves the exchange of DNA through direct cell-to-cell contact or through a bridge-like connection between two cells called a sex pilus. • The area where DNA is located is called the nucleoid • DNA is organized in one double stranded circular molecule, Bacterial DNA Bacterial cell Plasmid DNA Genomic DNA. our bodies contain thousands of different proteins which perform, Bacterial Transformation - .
