Study Notes
Genetic Engineering
- Genetic engineering is the transfer of a specific gene for a desirable trait.
- The basis for genetic engineering is the similarity of cells and cellular constituents of different organisms.
- Recombinant DNA technology combines genes in a test tube to form a hybrid DNA.
Traditional Breeding
- Through traditional breeding, genes of parents are mixed, and the desired gene comes with many others that may not have useful or desired traits.
Modern Biotechnology
- Modern biotechnology is the application of in vitro nucleic acid techniques, including recombinant DNA technology, and fusion of cells beyond the taxonomic family.
- It overcomes natural physiological reproductive or recombination barriers.
- It is not considered traditional breeding or selection.
The Discovery of Watson and Crick
- Watson and Crick proposed the double-helix structure for DNA, which explains how DNA replicates and how genetic information is expressed.
Golden Rice
- Golden rice produces high levels of beta-carotene in the endosperm.
- It was initiated by Dr. Ingo Potrykus and Dr. Peter Beyer.
- It uses phytoene synthase from E. uredovora and phytoene desaturase from daffodil (GR1) and corn (GR2).
Bt Eggplant
- Bt eggplant is a genetically modified eggplant that contains a gene from Bacillus thuringiensis (Bt) that produces a protein toxic to the eggplant fruit and shoot borer (EFSB), a major pest of eggplants.
- It is safe for humans, farm animals, and non-target insects.
Ringspot Virus Resistant Papaya
- The introduction of the viral coat protein gene results in overproduction of coat protein RNA and suppression of its synthesis.
Long Shelf-Life Papaya with PRSV Resistance
- This papaya is genetically modified to have a longer shelf life and resistance to papaya ringspot virus (PRSV).
- The expression of ACC synthase gene was silenced using anti-sense technology.
Carnation and Blue Rose
- Florigene developed the Moondust Carnation by transferring delphinidin genes from petunia.
- Suntory and Florigene developed the blue rose by transferring delphinidin genes from pansies, using the same technology for the blue carnation.
GloFish®
- GloFish® are genetically modified zebrafishes that express fluorescent proteins from jellyfish and sea anemones.
- They were developed by Zhiyun Gong at the National University of Singapore.
AquAdvantage® Salmon
- AquAdvantage® salmon is a genetically modified salmon that grows faster than non-transgenic salmon.
- It contains a growth hormone gene from Chinook salmon under the control of a promoter from an ocean pout.
