In preparation for the electrophoresis step in "DNA fingerprinting" the electrophoresis process cannot separate meaningfully massive molecules like whole chromosomes. By using restriction enzymes that break the chromosomes at known places DNA fragments of a wide variety of lengths that the electrophoresis process can separate meaningfully will allow a pattern to be generated that can identify different individuals.
What else can I help you with?
Where can one get his DNA extracted?
One can get his DNA extracted at a crime laboratory, at a police precinct, at a hospital, and even at home. DNA can be extracted by using a cotton swab in the inside of one's cheek or through a blood sample.
What food can DNA be extracted from?
DNA can be extracted from any living organism that has cells containing a nucleus, such as fruits, vegetables, meat, fish, and plants. Common sources for extracting DNA in a lab setting include strawberries, bananas, and onions.
Why chilled ethanol is added for DNA isolation?
to precipitate extracted DNA
What is extracted from cells for DNA microarray technology?
mRNA is extracted from cells for DNA microarray. the mRNA is then converted in the lab to cDNA this cDNA is allowed to interact with the probes on the microarray chip
Can DNA get extracted from a sterile cotton pad with blood?
Yes. You can get DNA from sterile cotton pad with blood for DNA finger printing.
Why can you see extracted DNA with naked eye?
No, you need a very powerful microscope.
How long will extracted DNA last if frozen?
Extracted DNA can last indefinitely if properly stored in a freezer.

Could DNA extracted from onion be different from DNA extracted from cauliflower why?
Although DNA is composed of the same four nucleotides in all organisms, the sequence of nucleotides is different for each species
What causes DNA to become fragmented?
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.
How is DNA extracted from blood samples?
DNA is extracted from blood samples by first breaking open the cells to release the DNA. Then, the DNA is separated from other cellular components using a series of chemical and physical methods. Finally, the purified DNA is collected and can be used for various genetic analyses.
What is extracted from cells for DNA microarray technology?
mRNA is extracted from cells for DNA microarray. the mRNA is then converted in the lab to cDNA this cDNA is allowed to interact with the probes on the microarray chip
Can DNA get extracted from a sterile cotton pad with blood?
Yes. You can get DNA from sterile cotton pad with blood for DNA finger printing.
Can the DNA from mitochondria be cloned for an extralarge dinosaur?
No, a full DNA strand has yet to be extracted from dinosaur remains
Can you suggest how DNA from whole plants may differ from that extracted from processed foods like corn chips or cornmeal?
DNA from whole plants typically contains intact genetic material, reflecting the full spectrum of the plant's genome. In contrast, DNA extracted from processed foods like corn chips or cornmeal may be fragmented or degraded due to processing methods like cooking, grinding, and chemical treatment, which can break down cellular structures and disrupt DNA integrity. Additionally, processed foods may contain additives or preservatives that can further complicate DNA extraction and analysis. Consequently, the quality and quantity of DNA from processed foods are often lower than that from whole plants.
