Biotechnology/ evolution

Humans directly change the DNA of organisms to produce a brand new trait. This is called:

• genetic engineering

• selective

  or

  artificial

  breeding

• gene therapy

• cloning

Humans make copies of genetic material (gene or DNA) or entire organisms This is called:

• genetic engineering

• selective

  or

  artificial

  breeding

• gene therapy

• cloning

Humans choose organisms to breed based on desired characteristics.

This is called:

• genetic engineering

• selective or

  artificial breeding

• gene therapy

• cloning

Humans using new medical treatment that to treat or prevent certain disorders and diseases. This is called:

• genetic engineering

• selective or

  artificial breeding

• gene therapy

• cloning

Many foods that I eat are GMOs (genetically modified organisms).

• TRUE

• FALSE

Farmers only planting seeds from the largest strawberries is an example of

• selective / artificial breeding

• genetic engineering

• gene therapy

• cloning

Scientist changes a gene that might cause cancer before someone develops cancer.

• selective / artificial breeding

• genetic engineering

• gene therapy

• cloning

The final product of the process shown above is an example of…

• restriction enzymes because the plasmid DNA and cell gene are combined from two different sources.

• recombinant DNA because the plasmid DNA and cell gene are combined from two different sources.

• a DNA fingerprint because the combination of DNA is now different from both the plant and the bacteria.

• a clone because the combination of DNA is identical to both the bacterium and the cell.

What is the purpose of restriction enzymes in the process shown above?

• Cut the DNA of the cell and the bacterial plasmid to create sticky ends that can be joined together.

• Cut open the cell wall of the bacterium to access the DNA.

• Seal the gaps between the sticky ends of the bacterial plasmid and the cell gene.

• Make the recombinant DNA resistance to antibiotics.

Which sheep will the cloned lamb be identical to?

• Sheep C because it was the foster mother.

• None of the sheep (A, B, nor C).

• Sheep A because it donated the DNA.

• Sheep B because it donated the egg.
