ANSWERS Oxidation.
During which phase of the cellular life cycle does DNA synthesis occur? - CORRECT
ANSWERS S phase.
What occurs during anaphase of mitosis? - CORRECT ANSWERS Centromeres are
severed, sister chromatids move apart, and are pulled toward opposite poles of the mitotic
spindle.
What is a highly coiled strand that is one of two duplicated portions of DNA in a replicated
chromosome? - CORRECT ANSWERS A chromatid.
What are fraternal twins also known as? - CORRECT ANSWERS Dizygotic twins.

What happens if a critical location on the master molecule receives multiple hits from ionizing
radiation? - CORRECT ANSWERS Normal cell function will cease, and the cell will die.
Which curve illustrates the radiation sensitivity of a particular type of cell? - CORRECT
ANSWERS Dose-response curve.
Which group of cells is least radiosensitive? - CORRECT ANSWERS Adult nerve cells.
What is the product of OH* + OH*? - CORRECT ANSWERS H2O2.
Which human is most radiosensitive? - CORRECT ANSWERS An embryo-fetus during
the first trimester of pregnancy.
What is the immediate cause of damage to DNA from ionizing radiation? - CORRECT
ANSWERS The free radicals produced by the interaction of radiation with water molecules.
What is the normal white blood cell count range for an adult? - CORRECT ANSWERS
5000 to 10,000/mm3 of blood.
One micron (μm) is equal to what measurement? - CORRECT ANSWERS 10-6 m.
Why is a periodic blood count not recommended for monitoring occupational radiation
exposure? - CORRECT ANSWERS Both biologic damage has already been sustained
when an irregularity is seen in the blood count and a blood count is a relatively insensitive test
that cannot accurately indicate doses of less than 10 cGyt.
