DNA can become fragmented due to various factors, including exposure to radiation, chemicals, or certain enzymes that break the DNA strands. Physical forces such as mechanical stress or shearing can also cause DNA fragmentation. In addition, natural cellular processes like DNA replication or repair can lead to DNA fragmentation as well.

What causes the DNA to precipitate and spool on the rod?
DNA precipitates and spools on a rod when it is mixed with alcohol. The alcohol causes the DNA to become less soluble in the solution, forcing it out of solution and forming a solid precipitate. The physical properties of the alcohol and DNA molecules are key factors in this separation process.
Which term describes as non-coding part of DNA that mau be a fragmented or nonfunctional gene?
Pseudogene.
What are the fragments making up the noncontinuous strand called?
The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.
What functional group in the DNA structure causes it to move only toward the positive poles?
The phosphate group in the DNA backbone has a negative charge due to its phosphate ions. This negative charge causes the DNA molecule to move towards the positive pole in processes such as gel electrophoresis.
What happens to a recombinant DNA when a successful cell transformation?
When a successful cell transformation occurs, the recombinant DNA is integrated into the host cell's genome. This allows the host cell to produce the desired protein encoded by the recombinant DNA. The transformed cell can now replicate and pass on the recombinant DNA to its daughter cells during cell division.
How does file become fragmented?
When the contents of a file are scattered across two or more noncontiguous sectors, the file has become fragmented

What characterises a cancer promoter?
A cancer promoter causes cells with DNA mutations to multiply and become tumors.
How does a file become a fragment?
When the contents of a file are scattered across two or more noncontiguous sectors, the file has become fragmented
What process is used to cut DNA into fragments?
DNA is cut into fragments using enzymes called restriction enzymes. These enzymes recognize specific sequences of nucleotides in the DNA and cleave the DNA at those points, creating fragments of various sizes.
What is an irreversible process during which the cell degenerates and the nucleus may become fragmented and protein denature?
Necrosis
What causes an error in DNA replications?
DNA polymerase pairing A with G
Why is cold isopropanol used rather than isopropanol at room temperature?
Cold isopropanol is used for DNA precipitation because it causes the DNA to become more insoluble and allows for better precipitation of the DNA from solution. Lower temperatures help the DNA strands stick together and form a visible precipitate, making it easier to isolate the DNA from the solution.
What are the fragments making up the noncontinuous strand called?
The fragments making up the noncontinuous strand in DNA replication are called Okazaki fragments. These are short DNA fragments that are synthesized discontinuously on the lagging strand during DNA replication.
Isopropyl alcohol causes DNA to do what?
Isopropyl alcohol can cause DNA strands to precipitate out of a solution, essentially forming a visible clump of genetic material. This property is used in DNA extraction techniques to isolate DNA from a sample by adding isopropyl alcohol to the solution, causing the DNA to become visible and separate from other cellular components.
What causes mutation in cells?
DNA polymerase
