DNA typing is done by scientist, finding markers in DNA samples from things like blood, hair or bone samples. They are found by designing small DNA probes that bind to the complementary DNA sequence. These bindings will create a very unique, distinctive pattern for an individual. They then take this pattern and match it up to evidence samples that were found at the scene. If one marker is the same, it doesn't give strong enough evidence, because one marker is not unique to each person, but when there are four, five or more, then the probability is very high that the evidence sample and the DNA sample taken are from the same person.
What else can I help you with?
How valuable are red blood cells in DNA typing?
Red blood cells do not contain a nucleus, which means they lack DNA. As a result, red blood cells are not useful for DNA typing. Instead, white blood cells, which do contain DNA, are typically used for DNA profiling and typing in forensic analysis.
Nuclear DNA typing can be most successfully accomplished on hairs that have been removed during which stage of growth?
Nuclear DNA typing is most successfully accomplished on hairs that have been removed during the anagen (growth) stage. This is because the root of the hair shaft contains the most intact nuclear DNA during this stage.
Can a DNA test be done after someone is dead?
Yes, a DNA test can be done on a deceased person using tissue samples such as hair, bone, or teeth. It is important to obtain permission from the appropriate authorities and follow legal procedures before conducting a DNA test on a deceased individual.
By what process is the DNA code duplicated?
DNA replication is the process by which DNA is duplicated. It occurs during the S phase of the cell cycle, where the DNA unwinds and the enzyme DNA polymerase adds complementary nucleotides to each strand, creating two identical copies of the original DNA molecule.
What is done to the DNA to make the bands visible in gel electrophoresis?
In gel electrophoresis, DNA is treated with a dye that binds to the DNA molecules, making them visible as bands under ultraviolet light.

Which of the DNA typing techniques do you think you would choose if you had to analyze a DNA sample?
I would choose polymerase chain reaction (PCR) for DNA typing, as it allows amplification of specific DNA regions for increased sensitivity and accuracy in analysis. PCR is a widely used technique due to its ability to generate large quantities of DNA from small samples, making it ideal for forensic and diagnostic applications.
The technology of DNA typing had its beginnings in 1985 with the work of?
Alec Jeffreys
Is identification based on blood typing more accurate than DNA testing?
No. Blood-typing is an older technology and far from conclusive since many people share the same blood types. DNA is at least as accurate as a fingerprint while blood typing only helps to narrow things down. Blood typing is more exclusionary in that if you have a different blood type, that proves innocence, but having the same does not prove guilt.
What percent of typing is done with the left hand?
56% :)
What do you press when your done typing ten in the bones on mythology?
nothing
Which technique has replaced simple blood typing for identifying criminals and determining parentage?
DNA testing.
Can the mobile phones locked on theft be unlocked?
It can be done by typing "984268"
How do you change your DNA into something incredible?
If that could be done it would already have been done. It cannot be done. You are what you are; you have already been formed according to the information in your DNA.
Nuclear DNA typing can be most successfully accomplished on hairs that have been removed during which stage of growth?
Nuclear DNA typing is most successfully accomplished on hairs that have been removed during the anagen (growth) stage. This is because the root of the hair shaft contains the most intact nuclear DNA during this stage.
Why cleavage of DNA is done in recombinant DNA technology?
Recombinant DNA technology is the most emerging technique for the production of DNA for the useful bio-materials like insulin. So to produce recombinant DNA two different DNA is rejoined. so cleavage is done to extract the desired DNA and then joined again.
Which technique did crime labs use prior to the development of DNA typing?
Before the development of DNA typing, crime labs primarily relied on techniques such as blood typing, enzyme analysis, and serological testing to analyze biological evidence. These methods could identify blood types or other biological markers but lacked the specificity and discrimination offered by DNA analysis. Additionally, fingerprint analysis and hair comparison were commonly used to link suspects to crime scenes. However, these techniques often had limitations in terms of accuracy and reliability compared to modern DNA profiling.
