The first class of drugs developed to treat AIDS, such as AZT, were known as reverse transcriptase inhibitors. They worked because they ____.

• targeted and destroyed the viral genome before it could be reverse transcribed into DNA
• bonded to the dsDNA genome of the virus in such a way that it could not separate for replication to occur
• bonded to the viral reverse transcriptase enzyme, thus preventing the virus from making a DNA copy of its RNA genome
• prevented host cells from producing the enzymes used by the virus to replicate its genome

Which of the following is required to make complementary DNA (cDNA) from RNA?

• restriction enzymes (endonucleases)
• gene cloning
• DNA ligase
• reverse transcriptase

Which of the following is not needed for PCR

• helicase
• primers
• DNA polymerase
• nucleotides

Which of the following is not true of restriction enzymes?

• restriction enzymes are found in bacteria
• restriction enzymes are needed for PCR
• restriction enzymes cut DNA as specific regions
• bacteria methylate regions of their own DNA that would be cut by restriction enzymes

______________ is a technique that scientists use to determine whether genes are on or off using presence of mRNA

• DNA electrophorhesis

• DNA microarray analysis

• Genetic Engineering

• Cloning
