- 1. Multiple Choice
This analysis technique is known as
Cloning
gel electrophoresis
chromatography
restriction enzmes
- 2. Multiple Choice
In preparation for an electrophoresis procedure, enzymes are added to DNA in order to
convert the DNA into gel
cut the DNA into fragments
change the color of the DNA
produce longer sections of DNA
- 3. Multiple Choice
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 came from both parents.
They have the wrong child, because her genetic information matches only that of the mother.
