Study Notes

Genome Editing

Genome editing is a technique used to make specific changes to the DNA of an organism.
Genome editing is used to introduce desired DNA into an organism, allowing for the introduction of new traits or characteristics.

Transgenics

Transgenics can be categorized into two groups: Germ line and Somatic transgenics.
Germ line transgenics involve the introduction of desired DNA into reproductive cells, resulting in the trait being passed on to future generations.
Somatic transgenics involve the introduction of desired DNA into non-reproductive cells, resulting in the trait only being present in the individual organism.

Gene Technology in Aquaculture

The advantages of gene technology in aquaculture include increased growth rates, improved disease resistance, and enhanced nutritional content.
Gene technology can also be used to improve the environmental sustainability of aquaculture practices.

GMOs

The source of donor DNA used in creating GMOs (Genetically Modified Organisms) can come from a variety of sources, including other organisms, viruses, or bacteria.
