DNA fingerprinting and Genetic Engin (Part 1)

Mr. Jones was killed in an accident. Afterwards, a former girlfriend filed a paternity suit claiming that Mr. Jones was the father of her child, and thus she was entitled to the man’s estate. Which sample of DNA would have to be from Mr. Jones if he were the child’s father?

• 2

• 3

• 4

• 5

Which suspect is likely guilty?

• Suspect #2
• Suspect #3

This laboratory procedure is known as

• CLONING

• gel electrophoresis

• chromatography

• use of a dichotomous key

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

A student performed a gel electrophoresis experiment. The results are represented in the diagram

below. Compared to the fragments at the top of the gel, the fragments at the lower end are

• larger, and move slower

• larger, and move faster

• smaller, and move faster

• smaller, and move slower
