19 Genetic Engineering.notebookApril 10, 2013Chapter 19 Genetic EngineeringThe genes we want to use is called the Target gene.We take it from one organism and put it into another organism.This is a 'cut and paste process'.It is placed into the second organism and is called Recombinant DNA.(The two different DNAs are combined)The altered organism is called a GMO (Genetically Modified Organism).R. Cummins1

19 Genetic Engineering.notebookApril 10, 2013Tools used in Genetic Engineering1. A source of DNA thetarget gene from species 1.2. A cloning vector bacterial plasmid (loop).3. Restriction enzymes these cut the DNA in acertain place as geneticscissors.4. DNA Ligase acts as agenetic glue.R. Cummins2

19 Genetic Engineering.notebookApril 10, 2013Restriction EnzymesThese enzymes will only cut DNA at certain places.For example one enzyme will only cut where the basesequence of GAATTC occurs.Species 1 DNASpecies 2 ATACTTGAATTCGGAAcutcutcutWhen the same enzyme is used for both speciesthe DNA will have complementary bases and will recombine easily.DNA LigaseAn Anabolic enzyme that stickscomplementary DNA bases together.R. Cummins3

19 Genetic Engineering.notebookApril 10, 2013The Process1. Isolation target gene and plasmid removed2. Cutting same restriction enzyme cuts both3. Ligation the ends are stuckR. Cummins4

19 Genetic Engineering.notebookApril 10, 20134. Transformation the uptake of DNA into a cell.5. Cloning produce identical copies of the bacterium.6. Expression the new DNA makes product.R. Cummins5

19 Genetic Engineering.notebookApril 10, 20133 Applications1. Bacterial genes into plants makes weedkiller resistant crops2. Human genes into animals genes added to produce a proteinin the sheep milk to treat emphysema.3. Human genes into bacteria genes added to make E.coli bacteria produce human insulinR. Cummins6

19 Genetic Engineering.notebookApril 10, 2013Ethical issuesGMOs in the environment can cause problems.e.g. some weeds are now weedkiller resistant.GMO as a food source could they cause harm to us?Will animals suffer from being modified?Will human zygotes be modified?R. Cummins7
