Catalog Number 166-0003EDU Week 7: pGLO Transformation Introduction to Transformation In this lab you will perform a procedure known as genetic transformation. Remember that a gene is a piece of DNA which provides the instructions for making (codes for) a protein. This protein gives an organism a particular trait. Genetic transformation literally means change caused by genes‚ and involves the insertion of a gene into an organism in order to change the organism’s trait. Genetic transformation
