Genetic Engineering

Gel electrophoresis enables scientists to

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

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.
