Question

2. When a small amount of DNA is found in human saliva on a glass at a crime scene, how do forensic scientists analyze the saliva to find a suspect?

Answer 1

Well the DNA is specific and unique to every person.

Answer 2

My lesson say any two people share, on average, 99.9% of their DNA, meaning that only 0.1% of your DNA is unique to you

Answer 3

wolfe8 is absolutely right just a small change...the DNA ''sequence'' is unique to every person

Answer 4

Then forensics will analyze that 0.1%

Answer 5

Would they do the gel electrophoresis process to analyze the saliva?

Answer 6

there are specific DNA sequences also called as variable no of tandem repeats which u obtain from ur parents and which they have obtained from their parents...so these sequences are specific to u and ur family only....dis is how they actually identify a person....

Answer 7

i dont think it would be electrophoresis..because to identify a person u need the sequence of DNA while electrophoresis gives u d molecular weight

Answer 8

Does this help? http://science.howstuffworks.com/life/genetic/dna-evidence2.htm

Answer 9

they may use DNA fingerprinting or maybe the microarray chip(i guess)
