MICROBIOLOGY FOR SURGICAL
TECHNOLOGISTS PRACTICE PAPER 2026
QUESTIONS WITH SOLUTIONS GRADED A+
●● Ethylene Oxide. Answer: Which of the following is a chemical
mutagen that the surgical technologist must follow precautions for when
used?
●● Direct Selection. Answer: A scientist creates conditions in the
laboratory that are conducive to the growth of a mutant strain. What is
the name of the test for identifying the mutant?
●● Lysogeny. Answer: During lysogenic conversion, what term refers to
the latent stage of the bacteriophage?
●● Nucleic acid hybridization. Answer: The technique of separating the
DNA strands of two different microbes to determine the similarity
between the DNA base sequences is:
●● True. Answer: Frameshift mutations result in the deletion or insertion
of one or more nucleotide pairs in the DNA strand: T or F
●● True. Answer: The mutation rate is the probability that a gene will
mutate when a cell divides: T or F
