Practice exam 4

  1. 1. BIOTECHNOLOGY What is the difference between CLONING and DNA CLONING?CLONING: Production ofidentical copies of an organismthrough asexual meansDNA CLONING (or Gene Cloning)Production of many identical copies of asingle gene.
  2. 2. USES FOR GENE CLONING1. Produce a large quantity of the gene’s product = Protein. Example: humulin or human insulin2. Learn about the function of the protein coded by thegene Example: Role of a particular protein in cancerprotection3. Make a transgenic organism Example: Pest resistant corn So do you think a transgenic animal is the same as a cloned animal?
  3. 3. BIOTECHNOLOGY DNA FINGERPRINTING or PROFILINGWhat are the 4 steps of fingerprinting? 1. Collect DNA 2. Amplify DNA if necessary using Polymerase Chain Reaction 3. Cut DNA in fragments at specific locations 4. Run an electrophoresis gel
