There are billions of base pairs in your chromosomes. So that is practically impossible to have a same photocopy of the DNA. So it is always possible to identify the individual from his DNA pattern. There is but one loophole in this statement. That is, you have same DNA pattern in identical twins and it is very difficult to identify them separately from their DNA pattern.
Hair is made of cells that include DNA. DNA is unique to each individual, ergo - you can identify someone with confidence based on DNa analysis of the hair.
DNA testing is used to identify things.
Radioisotopes are often used to label DNA molecules for detection purposes. This is achieved by incorporating radioactively labeled nucleotides during DNA replication or using radiolabeled probes that bind specifically to the DNA sequence of interest. By detecting the emitted radiation from the radioisotope, researchers can locate and identify the DNA molecules.
The unique sequence of DNA base pairs that can be used to identify a person at the molecular level is called a DNA fingerprint.
Fingerprint
The word DNA is a noun. It is a substance used to identify a person.
Only the root of the hair can be used. It has living cells which have DNA in their nuclei. This can bee used to identify someone as we all have unique DNA .
DNA or deoxy ribonucleic acid is such an important chemical because,it could be used to identify a person,and you are what your DNA is.Thank you!
A DNA fingerprint is a unique pattern of DNA fragments that can be used to identify individuals.
to prove or identify something or someone
The word "DNA" is a noun. It is a substance unique to each living person that can be used to identify them.
Since DNA is unique to each person, I'd say they used his own DNA.
