Biotechnology

What is this technique an example of?

• chromatography

• gel electrophoresis

• direct harvesting

• genetic engineering

The results of which laboratory technique are represented in the diagram?

• chromatography

• manipulation of genes

• genetic engineering

• gel electrophoresis

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

• Bob
• Sue
• John
• Lisa

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 

Which is the primary purpose of using restriction enzymes in gel electrophoresis?

• It allows the strands of DNA to be cut into various lengths for testing
• It restricts the number of base pairs that can be tested in a sample
• It makes the testing simpler by moving the strands into the gel faster
• It charges the DNA strands

Which DNA fragment bands move faster and farther in a gel electrophoresis? 

• there is no way to tell 
• the largest ones
• the smallest ones
• the lightest ones

Which chemicals are used to cut DNA into fragments for a gel electrophoresis procedure?

• enzymes

• molecular bases

• hormones

• ATP molecules

What is gene therapy?

• Introduce a functional gene into a person who lacks this

  gene

• Treating recessive

  diseases

• Both

What is recombinant DNA

• DNA from 2 different organisms combined

• DNA from 2 different ribosomes

• DNA that is separated out from a vector

Humans with genetic diseases can have a gene inserted into their body using a virus. This is called:

• Gene therapy

• Cloning

• DNA fingerprinting
