DNA Fingerprinting Review

What type of evidence is DNA?

• individual, trace, biological

• trace, physical, biological

• direct, biological, class

• class, biological, trace

Where in the cell is mtDNA found?

• nucleus

• mitochondria

• chloroplast

• endoplasmic reticulum

What are the steps of DNA fingerprinting?

• extraction, electrophoresis, STRs

• exon, STRs, PCR

• extraction, amplification, electrophoresis

• STR, PCR, RFLP

How does gel electrophoresis separate piece of DNA?

• charge

• size

• shape

• weight

Which is the DNA database?

• NIBIN

• CODIS

• AFIS

• FISH

This is a technique to amplify (replicate) DNA.

• STR (Short Tandem Repeats)

• PCR (Polymerase Chain Reaction)

• locus

• electrophoresis

What is the correct claim for this crime scene?

• Suspect 1 committed the crime.

• Suspect 2 committed the crime.

• Suspect 3 committed the crime.

• Suspect 4 commited the crime.

• Need more evidence to make a claim.

In gel electrophoresis, the largest DNA fragment will appear

• closest to the starting wells
• farthest from the starting wells
• three quarters away from the starting wells
• it depends on how many fragments there are

Variable segments of DNA, contain repeats of same sequence of nucleotides one after another

• Short Tandem Repeats (STR)

• Flanking Sequence

• Gel Electrophoresis

• Allele
