Unit 5 (Chapters 12 & 18) Potential FRQs
2000 Information transfer is fundamental to all living organisms. For two of the following examples, explain in
detail how the transfer of information is accomplished.
a. The genetic material in one cell is copied and distributed to two identical daughter cells.
b. A gene in a eukaryotic cell is transcribed and translated to produce a protein.
c. The genetic material from one bacterial cell enters another via transformation, transduction and
conjugation.
2002 Bacteria were cultured in a system that allowed for the continual addition of fresh nutrients and the
removal of waste products. Bacteriophage (virus) were added at the time shown and the following population
changes were observed.
2008 Regulation is an important aspect of all biological processes.
For the following process, describe the specific role of the regulator and discuss how the process will be altered
if the regulation is disrupted.
Process
Regulator
Cell cycle Cyclin
2011 (Form B) The cell cycle is fundamental to the reproduction of eukaryotic cells.
(a) Describe the phases of the cell cycle.
(b) Explain the role of THREE of the following in mitosis or cytokinesis.
Kinetochores
Microtubules
Motor proteins
Actin filaments
(c) Describe how the cell cycle is regulated and discuss ONE consequence of abnormal regulation.
2015 Both mitosis and meiosis are forms of cell division that produce daughter cells containing genetic
information from the parent cell.
(a) Describe TWO events that are common to both mitosis and meiosis that ensure the resulting daughter cells
inherit the appropriate number of chromosomes.
(b) The genetic composition of daughter cells produced by mitosis differs from that of the daughter cells
produced by meiosis. Describe TWO features of the cell division processes that lead to these differences.
