In preparation for gel electrophoresis, enzymes are added to DNA in order to
start protein synthesis.
cut the DNA into fragments.
change the color of the DNA.

The parents of a new baby believe they brought the wrong child home from the hospital. Gel electrophoresis was performed using DNA samples from the parents and the child. A section of the gel
electrophoresis results is shown below. Which conclusion is valid based on the gel electrophoresis results?
They have the correct child, because her genetic information is identical to that of the father.
They have the wrong child, because her genetic information does not match that of either parent.
They have the correct child, because her genetic information matches the genetic information from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
Which DNA fragment bands move faster and farther during gel electrophoresis?
the medium size fragments
the largest fragments
the smallest fragments
Why do the fragments of DNA in gel electrophoresis travel away from the negative electrode?
DNA is negatively charged so it is attracted to the positive end of the unit.
DNA is positively charged so it is to attracted to the negative end of the unit.
The agarose gel is negatively charged.
The agarose gel is positively charged.
Which suspect's DNA was found at the crime scene?
Suspect 1
Suspect 2
Suspect 3
None of these suspects
