Solution
-
The most common vector used for genetic engineering in plants is the Agrobacterium tumefaciens plasmid. It originally came from the bacterium Agrobacterium tumefaciens. The feature that makes this plasmid useful in genetic engineering is its ability to integrate its own DNA into the DNA of the host plant cell.
-
Pharm animals are genetically modified animals that produce pharmaceuticals in their milk, eggs, or blood, which are then harvested for human use.
-
Two methods that can be used to introduce genetic material to create transgenic animals are microinjection and viral vectors.
-
Three examples of transgenic animals discussed in lectures could be GloFish (fluorescent zebrafish), OncoMouse (mice genetically modified to develop cancer), and Enviropig (pigs genetically modified to digest phosphorus more efficiently).
-
The major concerns regarding genetically modified organisms as food are potential health risks to humans, potential harm to the environment, and ethical concerns about manipulating the genes of organisms.
-
Biopharmaceuticals are medical drugs produced using biotechnology. They include monoclonal antibodies, recombinant proteins, and gene therapies.
-
Schmeat is lab-grown meat, also known as cultured meat. The major limitation to this technology at the moment is the high cost of production.
