Identify the three steps involved in the polymerase chain reaction (PCR) process. Along with listing each step you should also explain what occurs during each step.

DNA technology uses what type of protein to produce fragments of DNA with predictable sequences at their ends?

The following is a segment of a DNA strand. Identify the mRNA sequence that would result from transcription of this segment. Be sure to label both ends of the strand as well as identify the sequence of the strand. 5′ – ATGGCATAGACTG – 3′ 3′ – TACCGTATCTGAC – 5′

In the eukaryotic cell, a single DNA sequence can produce multiple different proteins. A transcription product from this sequence is cut into fragments, with certain fragments retained and glued back together while other fragments are left out. This is an example of what type of gene regulation?

The process by which a bacterial cell engulfs a DNA fragment from the environment, and incorporates the fragments into its own chromosome is known as what?

In eukaryotic cells, once translation has completed the final product must sometimes undergo additional changes in order to be fully functional. Some of these changes include additional folding, removal and/or reattachment of certain portions of the product, and addition of other molecules to the product. This is an example of what type of gene regulation?

Where in the eukaryotic cell does translation generally occur?

Which of the following does not possess a repressor protein bound to its operator sequence in its natural state?

Which vessel(s) receive(s) blood from the right ventricle?

An Automated External Defibrillator (AED) is a portable electronic device that diagnoses and can correct an arrhythmia of the heart by administering a large electrical shock. A. State what first happens at the cellular level when the heart is “shocked” with an AED. 2 pts B. Shocking the heart this way can be successful in restoring normal sinus rhythm to a heart experiencing ventricular fibrillation. Explain why and how this occurs. (Hint- do not just say that shocking the heart restores sinus rhythm!). 3pts
