Transgenic Organisms - notes In addition to DNA fingerprints, biotechnology is also used to make…… _________________________ DNA ________________________ of DNA from __________ sources. How do you make recombinant DNA? 1. ____________ DNA from two sources 2. Cut both DNA with the same _______________________________________ DNA cut by restriction enzymes has ______________ 3. Mix the two DNA molecules together, sticky ends will match Once the recombinant DNA is made you can insert it into bacteria, the bacteria is now _______________________ Organism with _______________________ The bacteria _____________________, making many copies of the donor gene. In this case ____________ _______ bacteria are produced that are capable of producing ____________________. A transgenic organism is also known as a ….. _________ (Genetically Genetically Modified Organism Organism) Products produced by technology from genetic engineering include some _______________ and _____________________. Examples: 1. _______________________ • Insulin regulates the _________________________ _________________________. • The gene for human insulin is inserted into yeast or bacteria, from which large quantities of the human insulin are manufactured 2. _____________________ • Genes for making __________________________ are taken from ___________________(yellow ___________________ flower) and inserted into the genome of ______________ What is the benefit? • _____________________ in undernourished people in poorer countries is often caused by a lack of ______________________ which is produced by beta carotene carotene. 3. ______________________ • Bt is a _______________________ that is _______________ to some insects. In the lab, the gene that produces the toxic effect is inserted into the DNA of plants • Bt crops produce an insecticide protein thousands of times _______________________ than the chemical spray insecticides 4. ______________________ • rBGH is a genetically engineered version of a ______________________,, which is found in the pituitary gland of cows and _________________________________. • rBGH can increase cows’ milk production by as much as ________________.
