BIOL133 TEST 4 QUESTIONS AND VERIFIED
ANSWERS| 100% CORRECT
Biotechnology
use or alteration of cells for specific purposes
transgenic organisms
has DNA from another species
recombinant DNA
adding foreign genes to cells
gene targeting
moves a gene to a particular location
alpha1-antitrypsin
sheep produce this human protein to treat deficiency that causes damage to the lungs and liver
GMO monkey
shows promise for human gene therapy; transplanted gene is heritable
why are genetic technologies possible?
genetic code is universal
PCR
amplifying pieces of DNA to create many copies
PCR uses
forensics, medical tests, genetic tests
Restriction enzymes
, cut DNA at specific locations (scissors)
DNA ligase
attaches 2 pieces of DNA together (glue)
vectors
carry DNA to a new location; plasmids, bacteriophages, retroviruses
recipient cells
cells to receive DNA
Human recombinant example
human insulin produced through recombinant DNA technology
transgenic plant vectors
gene guns, Ti plasmids, viruses
transgenic animal vectors
chemicals that open membrane, liposomes, electricity, injection
what is the most genetically engineered crop in the US
soybeans
bioremediation
use of an organism's engineered abilities to remove toxins from the environment
phytoremediation
using plants as a bioremediation vector but don't have to dispose of the contaminated material
transgenic corn in Mexico
GM corn banned in Mexico; corn with genetically engineered genes found in the mountains in
2001
