Unit 8- Biotechnology

What causes DNA to make a bone cell instead of a stomach cell?

• the muscle cell has more DNA

• the chromosomal arrangement determines it

• DNA gets transcribed and translated to make the cell

• they have different DNA in them

When you use a gel electrophoresis machine to identify a suspect, what is this process?

• bacterial transformation

• DNA fingerprinting

• gene therapy

• cloning

If someone left a hair strand at a crime scene, how could we use it to identify the criminal?

• testing it for protein

• compare it to the hair color of the victim

• testing it for lipids

• doing DNA analysis on the hair strand

Why is DNA fingerprinting a reliable method?

• DNA sequences are unique making identification easy

• DNA is the same in most people so it helps put people in groups

• DNA can show the weight and height of someone

• DNA lasts forever and can't be destroyed

How have GMOs in agriculture helped the environment?

• it has required less water for animals

• its made us use less natural resources

• it has reduced diversity

• it has reduced use of toxic herbicides

Match the person to the blood sample.

• Jenny

• Bob

• Mike

• Lisa

What do restriction enzymes do?

• allows DNA to have an electrical charge

• it makes testing go faster

• it cuts DNA strands at different lengths

• it reads the genetic code and processes it

What does the agarose gel do in the gel electrophoresis machine?

• it allows different sized DNA to band at different rates

• it gives off a positive charge, allowing DNA to move fast

• it cuts DNA at different sizes so that it can go through

• it makes the DNA turn blue, purple, or red to read it

True or False: Longer DNA fragments run through quicker!

• True

• False

Why are stem cells used?

• They make it easier to analyze DNA.

• They help cells clone themselves.

• They can become any type of cell.

• They can alter all of your DNA.
