What would happen if a chemical interfered with the ability of RNA polymerase to bind to a DNA molecule?

• Transcription would proceed, and a protein would be produced.
• The DNA molecule would replicate itself.
• The RNA polymerase would cut the DNA molecule in half.
• Transcription would not take place, and the protein would not be produced.

Scientists involved in biotechnology sometimes insert the DNA of one organism into a second organism. Which of the following best explains why they do this?

• to stop the organisms' gene expression
• to create new species of organisms
• to make new cell membranes
• to cause the second organism to produce proteins

How can a person's muscle cells have the same exact DNA sequences as their nerve cells even though the look and perform completely different?

• The two different cells become mutated
• The proteins expressed in each cell are different
• They actually have different DNA in the two types of cells.
• The genome of the different cells changes
