The insertion of the human insulin gene into the bacterium escherichia coli allowed it to produce human insulin. which type of organism is e. coli?

E. coli here is a host cell.

In respect to this procedure, two things were used to carry out the process of human insulin production, namely a host and a vector.

In molecular cloning, a vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell. In the production of human insulin, the vector in this case was a plasmid, a small circular double stranded  DNA found in most bacteria, that is distinct from the cell's chromosomal DNA.

 This circular DNA is removed from the bacteria, cut open and DNA for producing insulin is inserted into it  then it is closed into a ring again. This recombinant DNA plasmid is then inserted into a host cell, such as E.coli which then makes the insulin protein together with its own proteins. 

the correct answer is c took the test on ed

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."

name and explain one of the event that occurs during meiosis that increases the variation in offspring even more than simple reproduction?
