Technique in which genetic engineering is acomplished
recombinant DNA technology
Recombinant DNA technology
A gene from one organism is removed and inserted into the DNA from another organism creating a trangenic
A unit of DNA that is associated with an inherited characteristic
What does a gene do?
Codes for a specific protien, which is associated with a particular function
Genetic engineering is used for...
- 1. vaccines

- 3. modification of crops
- 3. human growth hormones/Protopin
GMOs Genetically Modified Organisms
Food items that have been genetically engineered
- Two sequential cell divisions that result in the reproduction of the chromosome number to one-half
- because in sexual reproduction involves the
Does the FDA require GMOs to be labled?
No so it is nearly impossible for a consumer to determine whether their food has been genetically modified
Why can GMOs be bad for the consumer?
- There is a risk of allergic reations that do not occur when consumer eats a food that is not genetically modified.
- ex. sudden allergy to tomatoes (flavr savrtm)
What causes allegies in GMOs?
The presence of a Bt toxin. Although Bt toxin is approved by FDA it causes allergies in some consumers.
Technique in which a corrected version of the gene is delivered to cells containing the defective gene
Meiosis begins with a blank cell.
Diploid. (One of which chromosomes are present in pairs.)
The diploid cell divides into four blank cells
Haploid (one in which the chromosomes are not in pairs)
