The right answer is The digestion of DNA by restriction enzymes.
The fragmentation of the DNA is done by bacterial enzymes called restriction enzymes.
Restriction-enzymes (or endonucleases) recognize and cut the DNA into a specific sequence. These enzymes are naturally produced in bacteria as a defense against bacteriophages - viruses that infect bacteria. The bacterial restriction enzymes cut the DNA of the invasive bacteriophage while leaving the bacterial genomic DNA healthy and safe through the addition of methyl groups.
These enzymes are used in practice at the laboratory level to explore DNA.

Answer:
Robert Hooke was the first person to examine a slice of cork under a microscope. He saw little boxes or rooms and hence, gave the name cells to the structure. He called them cells because their structure was similar to small rooms which were called cells by the monks. Hence, cells are similar to little rooms in the structure.
However, there are many differences between the two as cells are living things but little rooms are non- living things. Each cell comprises of the same organelles whereas little rooms might not have the same components.
Answer:
Yes, mitosis is genetically identical.
Explanation:
when mitosis happens, the cells replicate their DNA so when the cell divides in 2, each cell contains the same chain of amino acids so yes the process creates 2 genetically identical cells
