What is the major difference in the production of transgenic bacteria, plants, and animals?

Flauer [41]

Answer:

Transgenic animals require a host to grow but transgenic bacteria and plants do not require host.

Explanation:

Transgenic organisms are the organisms in which foreign genetic material are introduced so that the transgenic organism can get some particular traits and characteristic.

The process of producing transgenic animals is different from producing transgenic plant and transgenic animals because in transgenic animals DNA from a cell is transferred into an enucleated oocyte.

Then this oocyte is transferred to the oviduct of a surrogate mother to raise the genetically modifies embryo but in plant and microbe, no host is required.

Do turkeys get sleepy from that thing in turkey that makes you sleepy?

VladimirAG [237]

Answer:

Turkey allegedly causes drowsiness because it is packed with a nutrient called tryptophan. Tryptophan is one of 20 naturally occurring amino acids—the building blocks of proteins. Because the body is unable to manufacture tryptophan on its own, it must be obtained from food protein.
