Genetic Engineering and Cloning

The engineering of organisms that are genetically identical is known as:

• Cloning

• Bacterial transformation

• Selective breeding

• Gene therapy

When fragments of DNA are connected from different sources, this creates:

• A plasmid

• A clone

• Recombinant DNA

• Fragmented DNA

Bacterial DNA that is often circular or in the shape of a ring is called a:

• Clone

• Plasmid

• Fragment

• Recombinant DNA

Organisms that have had DNA from other organisms inserted into their DNA to produce certain traits are called:

• Plasmids

• Clones

• Transgenic organisms

• Recombinant organisms

Which of the following is a medical application of genetic engineering?

• Inserting human DNA into bacterial DNA for insulin production

• Manipulating of DNA to produce glowing monkeys

• Engineering crops for greater nutritional content

• Modifying genes to achieve a desirable phenotype

Crops are often genetically engineered for certain traits such as:

• Longer shelf life

• Better appearance

• Increased crop yield

• Shorter growing season

• Insect resistance

Crops are often genetically engineered for improved traits. Such crops and organisms are called:

• Genetically modified organisms

• Clones

• Transformed

• Nutritionally improved

Using genetic engineering to treat or cure diseases is called:

• Bacterial transformation

• Selective breeding

• Gene therapy

• Alternative medicine

Despite the successful cloning of human embryos, much of this research has been halted due to:

• National laws prohibiting human cloning

• Insufficient funding

• Lack of experimental research

• Ethical concerns
