If the addition of one gene encoding a restriction endonuclease by horizontal gene transfer is beneficial or not is to be stated. Concept introduction: The restriction enzymes are also called as restriction endonucleases. The restriction endonucleases are used for the hydrolysis of the phosphodiester backbone present on the particular DNA sequence.

Please answer this asap. Thanks, You have discovered a new plasmid RK21 in a unique bacterial community. As a first step towardunderstanding this plasmid, you digest the plasmid with three restriction enzymes: SspI, XhoI andSmaI. You run the digested plasmid DNA on an agarose gel, along with an uncut sample of theRK21 plasmid DNA as a control.Unfortunately you forget to load a DNA ladder, and obtain the following results. Assumecomplete digestion of all samples or all the digests worked completely
