What cell organelle carries its own DNA passed down from the mother and is used to trace genealogy?

• ribosome

• golgi apparatus

• mitochondria

• vesicles

In order to manipulate genetic material, DNA must be extracted from cells. What is the correct order of the process used to manipulate DNA?

• enzymes inactivate proteins, buffering compounds break-down cell, alcohol to bring out DNA

• gelatinous mass of DNA broken down using buffering compounds, alcohol to remove DNA, enzymes to inactivate proteins

• buffering compounds to break-down cell, enzymes to inactivate proteins, alcohol to bring out DNA

• none of the choices are correct

The process where an electric current is used to separate nucleic acids based on size and is used in forensics is called

• gel electrophoresis

• cloning

• transgenic manipulation

• PCR

The process used to make copies of DNA when not much is available and is often used in forensics is called

• gel electrophoresis

• cloning

• PCR

• transgenics

The vector used in genetic engineering is a(n)

• bacterium

• adenovirus

• bacteriophage

• transgenic donator

Polymerase Chain Reaction

• Is used to make copies of specific regions of DNA

• Uses a special form of DNA polymerase and primers to copy DNA

• is used in crime scenes and paternity cases to compare DNA samples

• All of the choices are correct

• some of the choices are correct

The polymerase chain reaction is important because it allows us to

• Make many copies of a targeted segment of DNA

• Insert eukaryotic genes into prokaryotic plasmids

• Incorporate genes into viruses

• Make DNA from RNA
