DNA made from two (2) or more sources is called...

• Recombinant DNA

• Bacterial DNA

• Messenger DNA

• Artificial DNA

Which of the following is used to create recombinant DNA?

• Restriction Enzymes

• Amino Acids

• Genetic Proteins

• Messenger RNA

Which genetic engineering technique amplifies the number of DNA pieces in a lab setting?

• PCR

• Gel Electrophoresis

• Gene Therapy

• CRISPR

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

• PCR

• Gel Electrophoresis

• Gene Cloning

• CRISPR

Gel electrophoresis enables scientists to

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

Genetic engineering has been used to produce

• medicines.
• food animals.
• improved crops.
• all of these.

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

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.

Transgenic organisms contain

• genes from other species.
• cells of another organism.
• genes of only one parent.
• one or more human genes.
