To use DNA to identify a specific person accurately, you want to compare genetic markers that are unlikely to be shared with any other person.

What is the term for genetic markers that turn DNA segments on and off?
The epigenome refers to the markers that turn on and off specific genes. The markers themselves are named according to their chemical composition, ie. methyl-markers.
What is a sumaritan tiger?
a sumatrin tiger is a tiger found on the Indonesian island of Sumatra. Genetic testing have found unique genetic markers that have isolated them from mainland subspecies.
Why can DNA be used to identify people?
Every person in the world has different DNA to some extent. Humans all share 99.99% identical DNA, but there are certain groups of genetic markers that scientists have found that differ between each individual. A multitude of these groups are evaluated in both a sample from a crime scene and a control (taken from a subject) and these markers are compared. If a predtermined amount of these markers match, the DNA is considered a match. The accuracy of this is very good. The accuracy is in the 1:10,000,000,000 (10 billion).
Who can DNA technology allow us to identify a person parents?
DNA technology can allow us to identify a person's parents by comparing the individual's DNA to their potential biological parents. By analyzing the genetic markers and similarities between the DNA samples, scientists can determine if a person shares genetic material with their alleged parents, establishing a biological relationship. Techniques such as DNA sequencing and genetic profiling are commonly used for this purpose.
What is a gene tic marker?
A gene or DNA sequence having a known location on a chromosome and associated with a particular gene or trait. Genetic markers associated with certain diseases can be detected in the blood and used to determine whether an individual is at risk for developing a disease.
What if you sent human saliva to the dog breed DNA test?
The results would be voided because the genetic markers for the "breed" genetic or parental markers would not be present.
What is the term for genetic markers that turn DNA segments on and off?
The epigenome refers to the markers that turn on and off specific genes. The markers themselves are named according to their chemical composition, ie. methyl-markers.
How do forensics investigators use DNA fingerprinting to link a particular suspect to a particular crime scene?
Forensic investigators use genetic markers that vary from person to person. Thus, if all of the genetic markers in the DNA from a crime scene are identical to the genetic markers in the DNA from one of the suspects, that is good evidence that the suspect and crime scene DNA came from the same individual.
What role do gene markers play in genetic engineering?
its bdt here . gene marketers have a feel for what people want so they tell the genetic engineers
Scientists use a what to determine if a transformation was successful?
Scientists use a genetic marker to determine the success of a transformation. Genetic markers will change if the transformation has succeeded.
What is a sumaritan tiger?
a sumatrin tiger is a tiger found on the Indonesian island of Sumatra. Genetic testing have found unique genetic markers that have isolated them from mainland subspecies.
Is genetic screening and genetic testing the same?
The terms could be used interchangably but screening is usually a study of parental ancestry to determine if their are historical markers that would warrant genetic testing, karotyping.
What is the word for observable genetic traits/markers that conclusively proves two siblings do not have the same father?
The word for observable genetic traits/markers that conclusively prove that two siblings do not have the same father is called "non-paternity events." These markers are variations in the DNA that are unique to an individual, and can be used to confirm whether or not two people share a biological relationship. In the case of siblings, non-
What are genetics markers?
Genetic markers are areas on the chromosome which are in linkage disequilibrium with a known trait, ie they are inherited along with the trait. The markers do not have to cause the condition or trait to be observed, but they will always be inherited alongside the trait and therefore cna be described as a marker for that particular trait.
How are genetic markers related to transformation?
Genetic markers make it possible for researchers to mix recombinant plasmids with a group of bacteria. Add enough DNA to transform one cell into a million and still be able to "find" that cell.
What is the genetic link for myopia?
genetic markers that may be associated with genes for myopia have been located on human chromosomes 1, 2, 12, and 18. There is some genetic information on the short arm of chromosome 2 in highly myopic people.
Can a child and alleged father have no common DNA markers?
NO, as half of the genetic material for the child is from the father they will always have similar DNA patterns.
