A scientist is studying a gene (grn) carried by a bacteriophage that allows a host bacterium to produce a green metabolic product before lysis. The scientist has four bacteriophage mutants for this gene. Mutant 1 has a nonrevertible mutation in grn while Mutants 2, 3, and 4 each have a revertible mutation in grn. After plating pairs of mutants and subsequent coinfection of host cells, the scientist observed the following:
I.Mutants 1 and 2: no green product
II.Mutants 1 and 3: very rare green product
III.Mutants 1 and 4: rare green product

Which of the following is NOT consistent with these observations?
◦ A partial deletion in Mutant 1 overlaps a base-pair substitution in Mutant 2.
◦ Mutant 2 has a base-pair substitution at a different site than Mutant 3.
◦ Mutant 3 has a base-pair substitution at a different site than Mutant 4.
◦ Mutant 1's deletion is closer to the base-pair substitution in Mutant 3 than it is to the base-pair substitution in Mutant 4.
◦ A green product should be observed if coinfection occurs with mutants 3 and 4.

Did you know?

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease. However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.
