Forensic DNA

Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?

• DNA is negatively charged so attracted to the positive end of the unit

• DNA is positively charged to attracted to the negative end of the unit

• the agarose gel in negatively charged

• the agarose gel is positively charged

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

What determines the code, or information, of a DNA molecule?

• the shape (structure) of the nitrogen bases

• the order (sequence) of the nitrogen bases

• the color of the nitrogen bases

• the frequency (number) of nitrogen bases

The name of the FBI's DNA database is:

• CODIS

• PCR

• RFLP

Why is non-coding DNA the best for identifying individuals?

• It has to code for important proteins.

• It is not important for the cell's production of protein and thus can have different amounts for everyone.

• It is not important so it is not the best.

Which process uses long fragments of repeating nitrogen bases to create a unique DNA fingerprint for an individual?

• RFLP

• STR

• PCR

• Recombinant DNA

What does PCR stand for?

• Poly-ambiguous chain reaction

• Pentahedral corrosion remnant

• Polymerase chain reaction

• Peroxide corrosion remnant
