Genetics
Question | Answer |
---|---|
Ti Plasmid | "tumor inducing" that naturally occurs in the bacterium A. tumefaciens. Cells are removed. |
Electroporation | a brief jolt of electricity opens transient holes |
Microinjection | using a microscopic needle |
Particle Bombardment | gun like device shoots tiny metal particles, usually gold or tungsten, coated with foreign DNA |
Transplastomics | targets genes in the chloroplast because they have their own DNA |
1 advantage to Transplastomics | can give high yields of protein products |
1 disadvantage to Transplastomics | difficult to find vectors |
Rhizosection | adding a transgene attached to a piece of DNA that stimulates secretion from roots into a liquid medium - used to create drugs in a method that is easier to extract |
Bioremedation | uses bacteria or plants with greens that produce the ability to detoxify certain pollutants |
Agriculture Biotechnology | altering DNA, organelles, or cells of organisms that we use for a variety purposes |
Transgenic | organisms formed with the host bacteria and an added gene |
Artificial Seeds | an embryo grown in a cell is combined with nutrients and hormones and encased in a gel like substance (callus) |
Somaclonal Variation | a mutant somatic cell is part of a callus grows into a plant with a new trait. |
3 Steps in Biotechnology | 1. Identify and breed an interesting trait. 2. Then test the new varieties in various habitats and seasons to determine the best growth conditions. 3. Seeds are distributed by growers. |
Chlybridization | a chloroplast is introduced into a cell liposome |
Clonal Propagation | cells are cultured and grown into genetically identical plants |
Cybridization | cells are fused, and the nucleus of one is destroyed by radiation |
Mibridization | a mitochondrian is introduced into a cell liposome |
Mutant Selection | cells in a culture are exposed to toxin, resistant surviving cells are used |
Protoplast Fusion | two cells from different species have their cell walls removed and are fused, a hybrid is regenerated |
