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.
How long does DNA in hair last before it degrades?
DNA in hair can last for centuries before it degrades, as hair is a durable source of genetic material.
Does soil have DNA?
Soil itself does not have DNA. DNA is found in living organisms such as plants, animals, bacteria, and fungi that may be present in the soil. DNA from these organisms can be extracted from soil samples for analysis.
How long does DNA last in hair and what factors can affect its preservation?
DNA can last in hair for a long time, potentially thousands of years under the right conditions. Factors that can affect its preservation include exposure to sunlight, moisture, heat, and chemicals.
What is the function of the lysis solution in DNA extraction?
The lysis solution breaks open the cells and releases the DNA, allowing it to be extracted for further analysis.
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
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
How is DNA extracted from blood samples?

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
How long does DNA last?
it dipends on which part of the body it comes from
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
How long does DNA in hair last before it degrades?
DNA in hair can last for centuries before it degrades, as hair is a durable source of genetic material.
Why is buffer HB used in DNA extraction?
It serves to break the tissue apart so the DNA can be subsequently extracted.
How is an extracted DNA inserted into a new molecule?
Extracted DNA can be inserted into a new molecule through a process called molecular cloning. In this process, the DNA of interest is first integrated into a vector, which is a small DNA molecule capable of replicating inside the host cell. The new DNA construct can then be introduced into a host cell, where it will be replicated along with the host DNA.
