Why do scientists extract DNA?
Scientists extract DNA from organisms to study genetic information, including gene sequences, mutations, and genetic relationships. This information can help in various fields such as medicine, agriculture, and forensics by providing insights into diseases, breeding programs, and identifying individuals.
Where can scientists get DNA from?
Scientists can obtain DNA from various sources such as blood samples, saliva, hair roots, skin cells, and tissue samples. These samples contain cells that can be used to extract and analyze DNA. Additionally, DNA can also be obtained from organisms such as bacteria, plants, and animals for research purposes.
Where can forensic scientist extract DNA from in a crime scene?
Forensic scientists can extract DNA from various sources found at a crime scene, such as blood, saliva, hair follicles, skin cells, and semen. These samples are collected carefully and analyzed in the lab to identify potential suspects or victims based on their DNA profile.
How are scientists able to compare DNA from bones or teeth to that found in hairs on a hairbrush?
All DNA pairs of the human body are 100% identical, regardless of where the sample is taken from. Hair cells have the same DNA structure as skin cells, saliva, sperm, etc. Every humans DNA is unique, this allows scientists to identify who a specific sample belongs to.
Can you extract DNA from ear wax?
Yes, it is possible to extract DNA from ear wax as it contains skin cells that can be used for genetic testing.

In teeth do forensic scientists collect DNA from the mitochondria or the nucleus?
Any of the pulpy matter can be used to extract DNA. Not so with the enamel.

How is anything genetically modified?
Scientists have the means to extract the DNA strand from a cell. Once the DNA strand is removed, it can be altered, then placed back into the cell. When the cell divides and multiplies - the new copies will retail the altered DNA rather than having the original.
Why do scientists have to have a female mosquitoes to clone a dinosaur?
Scientists believe they can extract dinosaur DNA from a fossilised female mosquito,in an attempt to clone a dinosaur.A female mosquito is being used because, only the female feeds on blood.
Can you extract DNA from an onion?
si
Can you extract DNA from fruit?
Yes.
Can extract DNA from fruit?
Yes.
Why do scientists use the white blood cell when extracting DNA in gentic screening?
White blood cells (unlike red blood cells) have nuclei containing genetic material. Since DNA is present within the white blood cells and since blood is easy to obtain from the body, scientists use white blood cells to extract DNA

What led scientists accepting mendel idea?
Scientists discovered chromosomes in DNA
