DNA fingerprint - comes from saliva 

DNA- Deoxyribonucleic 

Single cell- basic unit of living matter 

Genes-a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

PCR(Polymerase chain reaction) -Technique used for copying DNA molecules 

Geneticist-A scientist who studies genes 

Polymorphic regions-The region showing the most extreme variation 

PCR- polymerase chain reaction .

There are two different kinds of fingerprints , a digital fingerprints comes from the raised ridges of skin that run in patterns of curving lines along the tips of your fingers .

The second DNA fingerprint comes from your saliva EX: Licking a envelope.

There 75 trillion cells make up in the human body.

 In the human body 46 chromosomes float in a watery nucleus . The threadlike strands are made of protein and DNA molecules 

 The 46 chromosomes come in two sets 26-mother 

26-father and they sets determine what people would look like when they get older 

DNA determine our hair, eye,and skin color and height . 

Dna code consists of A(adenine)-T(thymine) and G(guanine)-C(Cytosine) 

All the genes .

DNA is found in almost every human cell ,including skin and blood.
