Please use the following information to answer the question(s) below.
A hypothetical bacterium swims among human intestinal contents until it finds a suitable location on the intestinal lining. It adheres to the intestinal lining using a feature that also protects it from bacteriophages and dehydration. Fecal matter from a human in whose intestine this bacterium lives can spread the bacterium, even after being mixed with water and boiled. The bacterium is not susceptible to the penicillin family of antibiotics. It contains no plasmids and relatively little peptidoglycan.
-In which feature(s) should one be able to locate a complete chromosome of this bacterium?
1) nucleolus
2) pili
3) endospore
4) nucleoid
A) 4 only
B) 1 and 3
C) 2 and 3
D) 3 and 4
E) 2, 3, and 4

Question

Quizplus · Accepted Answer

The presence of a complete chromosome in a bacterium would be located in the nucleoid, which is a region of the cytoplasm where the chromosome is located. The bacterium described in the scenario does not have nucleoli, pili or endospores containing genetic material. Therefore, the correct answer is D, 3 and 4, which includes endospores and nucleoids.
