When DNA is manipulated and moved from one source to another it is known as

• genetic engineering
• electrophoresis
• gene therapy
• GMO

Making changes in the DNA of an organism is

• selective breeding
• artificial selection
• genetic engineering
• genetic transformation

Gel electrophoresis enables scientists to

• separate DNA fragments.
• combine DNA fragments.
• count the genes in DNA.
• insert DNA in cells.

Polymerase chain reaction is used to

• determine the sequence of DNA.

• make copies of a DNA sequence.

• selectively breed plants and animals.

• produce mutations in bacteria.

Which is used to cut DNA molecules at specific points?

• gel electrophoresis
• PCR analysis
• a restriction enzyme
• recombinant DNA

What is a GMO?

• An organism that has had its DNA modified by humans

• An organism missing a chromosome

• Epigenetics

• A genetically identical organism

• b). Bacteria

• c).Virus

• d).Fungi

Restriction Enzymes are . . . 

• proteins
• DNA
