What is recombinat DNA?
Answer- C) DNA that carries genes from different organisms.
Recombinat is a artifical process , making place in laboratory, where the host genome is added with genes from other organism , hoping to get useful products, better adaptation to stress conditions. It is useful in agriculture industry , medicine and many more fields.
please give a thumbs up!!!!!!!!!!thank you!!!!!!!!

Flagellar phase variation occurs in Salmonella and involves several genes and DNA sites. Several different mutations were made in those genes/sites to determine the effects on phase variation. For each mutation listed below, which flagellin is synthesized when the invertible region is in the position indicated? Note: A null mutation results in the production of a nonfunctional product or no product at all. Assume base changes result in inactivation of that site so it can no longer function. A nonpolar...
