During transformation, a cell

• is treated with radiation.
• has two genetically different parents.
• has foreign DNA inserted in its chromosome.
• has parents of different species.

molecular scissors that "cut' DNA

• plasmid

• restriction enzymes

• Ribose

• mutations

Gel electrophoresis enables scientists to

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

Which genetic engineering technique separates DNA fragments based on their size?

• PCR

• Gel Electrophoresis

• Always bad for you

• Always free of pesticides

• Always selectively bred

This technique used to analyze DNA involves the
