Which form of Biotechnology is MOST LIKELY to be used in forensics?

• animal cloning

• DNA fingerprinting

• genetic engineering

• selective breeding

Which is a theoretical benefit for cloning?

• The variation in a species could be increased

• Organisms with new traits can be produced

• Genetic diseases in humans can be cured

• Populations of endangered species could be increased

A gene for human growth hormone (HGH) production is taken from human DNA and inserted into a bacterial plasmid. Which statement explains why bacteria are used as host organisms for creating recombinant DNA in this example?

• They replicate quickly, with each cell producing HGH

• They can be injected directly into patients to produce HGH

• They digest the gene and metabolize the nucleotides into HGH

• They provide the HGH production gene that can be inserted into a human cell
