Making changes in the DNA of an organism is

• selective breeding
• artificial selection
• genetic engineering
• genetic transformation

What process is shown in the picture?

• Gene therapy
• Cloning
• DNA Fingerprinting
• Gene Splicing

Putting the gene for bioluminescence into a fish is an example of...

• Genetic Engineering
• Selective Breeding
• Artificial Selection
• Gene Mutation

This laboratory procedure is known as

• CLONING

• gel electrophoresis

• chromatography

• use of a dichotomous key

In preparation for an electrophoresis procedure, enzymes are added to DNA in order to

• convert the DNA into gel

• cut the DNA into fragments

• change the color of the DNA

• produce longer sections of DNA

A student performed a gel electrophoresis experiment. The results are represented in the diagram

below. Compared to the fragments at the top of the gel, the fragments at the lower end are

• larger, and move slower

• larger, and move faster

• smaller, and move faster

• smaller, and move slower

This technique used to analyze DNA involves the

• synthesis of new DNA strands from subunits

• separation of DNA fragments based on size

• production of genetically engineered DNA molecules

• removal of defective genes from DNA
