• Make them more nutritious

• Make them larger

• All answers are correct

A circular piece of DNA, found in bacteria, is called:

• A plasmid

• mRNA

• Ribosome

• Nucleotide

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

• genetic engineering
• electrophoresis
• gene therapy
• GMO

Plasmids, yeast, and viruses are known as ____________.

• restriction enzymes
• vectors
• genetically modified organisms
• bacteria

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

Transgenic organisms contain

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