What is DNA? Where is it found?
 DNA is a genome and it is located in the nucleus. There also small amounts of DNA in mitochondria.
What is mitochondrial DNA?
Mitochondrial DNA is the DNA that is located in the mitochondria.
What is CODIS? How does it work?
The generic term that is used to recount the FBI's program support for the DNA databases. The CODIS generates the investigative leads in all crimes that would contain biological evidence.
What are complimentary base patterns? Why are they important? Compliment bases mean that guanine is always paired to the cytosine, adenine is paired with thymine. They are referred to nucleotides. It is important because the four bases are components of your DNA. The chemical interaction is what forms a double helix.
What is RFLP? What are some of the limitations of this technique?
The RFLP is the method of using molecular biologists
