Which of these will deactivate in the presence of the molecule they are named for?

Define nonsense mutation. Then give an example of this type of mutation, both at the DNA and protein level, and explain what effect this mutation would have on the protein’s function.

Which of the following is true of the lagging strand?

True or false: Eukaryotic cells need additional molecules, called transcription factors, to bind to a promoter sequence before transcription can begin.

A segment of DNA that marks where transcription for a gene should end is called what?

The process by which a virus picks up bacterial DNA during its creation, injects this bacterial DNA along with its own genetic material into a new host cell, and this foreign bacterial DNA is incorporated into the new bacterial host is known as what?

Which of the following was the conclusion reached by the Meselson and Stahl experiment?

The following image show a gel at the end of gel electrophoresis. Well 1 was filled with a control, the exact DNA sequence we are looking for. Wells 3 and 5 were filled with DNA extracted from two different samples. Which of these samples contains the DNA sequence we are looking for? Choose all that apply.    

DNA packing, X inactivation, and DNA chemical modification all affect gene expression by affecting the DNA chromosome itself. Explain a) what effect these have on the DNA chromosome (in general, no need to explain all three in detail) and b) how this effect regulates gene expression.

The following image show a gel at the end of gel electrophoresis. Well 1 was filled with a control, the exact DNA sequence we are looking for. Wells 3 and 5 were filled with DNA extracted from two different samples. Which of these samples does not contain the DNA sequence we are looking for? Choose all that apply.
