Your Mother and Father have diffrent roads in there DNA from there Parents, and so-on! Ok then there is the main element or Highway is the "Human" Element All 3 made you into what and who you are! In most cases you developed stronger elements over another. Such as you may Look like your fathers Mother in the face but have your mothers likeness or tempperment and personality! You nay be a creative type and focus on art and here you have a Aunt that is the only one that paints or draws! DNA is unic and only you have a unic strain or road thats all yours.. Your Siblings may have closely similar DNA but even they have developed something unic or diffrent than you!
The Functions are al combined while you where in the womb and those functions start in you blood and go from there....

Types Of DNA tests

If you are asking about forensic DNA testing then : There have been two main types of forensic DNA testing. They are often called, RFLP and PCR based testing, although these terms are not very descriptive. Generally, RFLP testing requires larger amounts of DNA and the DNA must be undegraded. Crime-scene evidence that is old or that is present in small amounts is often unsuitable for RFLP testing. Warm moist conditions may accelerate DNA degradation rendering it unsuitable for RFLP in a relatively short period of time.
PCR-based testing often requires less DNA than RFLP testing and the DNA may be partially degraded, more so than is the case with RFLP. However, PCR still has sample size and degradation limitations that sometimes may be under-appreciated. PCR-based tests are also extremely sensitive to contaminating DNA at the crime scene and within the test laboratory. During PCR, contaminants may be amplified up to a billion times their original concentration. Contamination can influence PCR results, particularly in the absence of proper handling techniques and proper controls for contamination.
PCR is less direct and somewhat more prone to error than RFLP. However, PCR has tended to replace RFLP in forensic testing primarily because PCR based tests are faster and more sensitive.

DNA basics

Deoxyribonucleicacid. it is present in the nucleus of the the cell. it is responsible for ur genetic make up and hereditary mental characteristics. during the process of reproduction the child inherits 50 % of his genetic make up from each of the parents.

a lot of smart people have answered it correctly.
To add,

DNA structure was explained by Watson & Crick using X ray diffraction model.
this model explains the Semi- conservative model of DNA very well.

DNA is like a rope staircase which is helically coiled.
The sides of this staircase are made up of sugars and phosphates and the rungs are made up of a pair of nitrogenous bases, the pair is joined by weak hydrogen bonds.
The N bases - Adenine which always pairs with Thymine
Cytosine which always pairs with Guanine

After every 10 base pairs there is a tun of the helix.

S ..A ... T...S
P P
S.. C ....G..S
P P

the sugar in DNA is deoxyribose
consits of two parallel chains held together by the pairing of bases between adjacent chains
Four different bases found in nucleic acids-
adenine
thymine
guanine
cytosine

DNA stores inherited info so the types of proteins can be manufactured in a cell
