What was the purpose of the Human Genome Project

• to sequence all of the genes in humans

• to find every disease in humans

• to name all of the nucleotides in humans

• to project all of the human's into a genome

What technique is used for separating DNA fragments?

• Gel electrophoresis

• Chromatography

• Transformation

• Transduction

The DNA molecule to which the gene of interest is integrated for cloning is called

• Transformer

• Carrier

• Vector

• Template

The cutting of DNA at specific locations became possible with the discovery of

• Selectable markers

• Probes

• Restriction enzymes

• Ligases

What is the purpose of PCR?

• To produce millions of copies of DNA.
• To produce millions of copies of a specific region of DNA
• To add nucleotides to a DNA sequence
• To watch polymerase work.

Based on these results whose blood was found in the blood stain at the crime scene?

• Bob
• Sue
• John
• Lisa

Which suspect is likely guilty?

• Suspect #1
• Suspect #2
• Suspect #3

DNA fingerprinting works because

• Most genes are dominant
• All organisms contain RNA
• The most important genes are different among most people
• No two people, except identical twins, have exactly the same DNA 

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

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
