The discovery of the structure of DNA and the development of biotechnologies to genetically modify organisms Flashcards
How was GMO created by the use of Recombinant DNA technology
a nucleus is extracted from a cell of the individual to be cloned, then inserted into an enucleated host egg for eg, dolly the sheep
What is cloning in terms of GMO?
Reproductive cloning
Joining Dna molecules from two different species
What are some advantages of GMO
Purpose of GMO
To increase crop yield
Increase nutrient composition and food quality
Increase pest resistance
What are some concerns of GMO?
Concerns
* Lack of regulation of genes
* Possible long term side-effects on organisms and consumers
* Errors resulting in mutations or disruption to biological processes
What is DNA?
DNA is a molecule that is all in the chromosomes of living things, which is in the structure of a double helix. Dna is composed of nucleotides that are in complementary bases (guanine, cytosine, adenosine and thymine).
