What is Recombinant DNA?

Recombinant DNA may be defined as the methodology of adjoining DNA molecules from two different sources and inserting them into a host organism, to synthesize products for human use. It involves the principle of recombinant DNA technology.

DNA that has been copied into an mRNA strand is a normal process of transcription. A plasmid and restriction enzyme are the tools of recombinant DNA technology.

A bacterial gene never holds a target plasmid, while a bacterial plasmid always holds a target gene inside it.

Therefore, the option that best describes Recombinant DNA is a bacterial plasmid with a target gene inside it. Thus, the correct option is A.

name the main nitrogen-containing compound found both in plants and in animals​

Answers

Answer:

Soil contains nitrifying bacteria that are crucial in converting nitrogenous wastes of dead and decaying matter of plants and animals to ammonia.

The most redox potential of soil nitrogen, ammonia, is transformed into its most oxidized form, nitrate, by nitrifying bacteria. By preventing soil nitrogen losses from leaching and nitrate denitrification, this is crucial for the function of the soil ecosystem.

What nitrogen compound found in plants and animals​?

The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals. The ammonia is subsequently changed into compounds that include ammonium. This is how the formation of ammonium compounds is aided by animals and plants.

Nitrification, which turns ammonia into nitrite and then nitrate, is a vital stage in the worldwide nitrogen cycle. Only prokaryotes perform aerobic nitrification, which makes up the majority of the process.

Therefore, The nitrifying bacteria found in soil are essential for producing ammonia from the nitrogenous waste products of dead and decaying plants and animals.
