How is the DNA fingerprint different from the other fingerprints?
Happidancer
DNA "fingerprinting" actually has nothing to do with fingerprints. Since fingerprints have been used in American courts since the Jennings case in 1911, maybe they used the term "DNA fingerprint" to help people grasp the concept of comparing two samples side by side, trying to find similarities and differences between them.
Fingerprints are actually more unique than DNA. Identical twins (and other identical multiples) have identical DNA but different fingerprints. Every finger is different than every other finger in the entire world - including the other fingers on the same hand.

Is a fingerprint better than DNA?
Both identify a person, the DNA more conclusively because fingerprints are often smeared or partials. A fingerprint has one advantage over DNA if it can be classified as where and when it was made, which can establish a person's presence in a given circumstance. For example, if a fingerprint is in the blood on a weapon, it could only have been made after the blood was there.
Why do siblings have different fingerprints?
fingerprints are different in everyone no matter if related or not , Because they are determined by random events in the womb not DNA. So even identical twins should have different fingerprints.
Different persons have different DNA fingerprints because?
they have different numbers of the same VNTR.
What are fingerprint's?
Variation in humans is the pattern of ridges in the skin of the finger prints.However, fingerprints are used to hold on to things. They were not actually made to ID people. We just have come up with this ID when we realized that no two people have the same finger prints. We have used other methods to ID, including DNA tests and retinal scans.
A pattern of bands made up of specific DNA fragments is a?
DNA fingerprint
Why is DNA sometimes called the fingerprint inside your body?
because everyone has different DNA and different fingerprints.
What are two different uses of DNA fingerprint?
The DNA fingerprint is used in many fields. DNA fingerprints are commonly used in forensic science. Also, the Human Genome Project utilized DNA fingerprints to map the entire human genome.
When comparing the DNA fingerprints of a parent and child the parent's DNA fingerprint must have?
DNA bands that match those in the child's fingerprint and that aren't from the other parent.
What effect does heredity have on fingerprint characteristics?
DNA does not affect fingerprints. Identical twins- people with the exact same DNA- have different fingerprints. Fingerprints (and toe, lip, or any other -print your body has) form in the womb at random.
How is DNA fingerprinting biotechnology?
You use computers to scan fingerprints, and computers is technology. This technology is biotechnology, because everyone has different fingerprints, and it depends on his or her genes for the exact form that the fingerprint takes.
Do children's fingerprint have the same DNA as adults?
Fingerprints don't have DNA... a fingerprint is simply the imprint of the ridges on the skin of the finger. Cells contain DNA, and your genetic code (DNA) stays the same throughout your life, it does not change when you become an adult.
What method is used to make DNA fingerprints?
A method known as RFLP (restriction fragment length polymorphism) analysis can be used to make a DNA fingerprint.
How does a blood test connect two siblings with a the same mother?
A DNA sample is extracted from a swab taken from the mouth of each sibling. The resultant DNA 'fingerprints' are compared to a sample fingerprint of the mother's DNA. They should contain half the DNA fingerprint of the birth mother.

The presence of various-sized fragments of DNA
Do people have different DNA fingerprints?

How do experts use DNA fingerprinting to analyze evidence in crimes?
There are three types of prints on fingers. The whorl, arch and loop. These three can make up fingerprints of people.
