February 3, 2010 What is genetic engineering? The process of manually adding DNA to an organism The goal is to add one or more traits not already found in that organism Also called genetic modified organism (gmo) Gm = genetic modification How it works Agrobacterium tumefaciens – soil bacterium that caused crown gails (extra tissue growth Bacterial Plasmid o Ring of DNA o Can go between species o Its job is to avoid new gene to target genome o Changes the genotype of another organism How do you get a new gene into a plasmid? Plasmid ring of DNA with original DNA o In that DNA (sequence od nucleotides) o Use restriction enzyme used to cut open strand but will only cut when it sees a certain order of nucleotide o Often the enzymes cuts crooked o Now you stick in a new gene o Use “stickies” to stick it back together o You need to get the nucleotides to match o Now you have the plasmid with the new gene inserted right in the middle Steps to genetic engineering
