Exam 1: Bacterial Cell Structure, physiology, Metabolism, and Genetics

The nuclear membrane in prokaryotes is:

The Gram stain is a routine stain used in bacteriology to determine gram-positive and gram-negative bacteria based on the:

The three basic shapes of bacteria include all the following EXCEPT:

Prokaryotic cells have which the following structures in their cytoplasm?

Some Clostridium sp.are examples of this class of organism because they can live in the presence of oxygen but do not use oxygen in its metabolic processes.

In the laboratory,the clinical microbiologist is responsible for all the following EXCEPT:

Genes that code for antibiotic resistance are often found on extracellular,small,circular pieces of DNA.These DNA pieces are called:

What process involves transferring or exchanging genes between similar regions on two separate DNA molecules?

To survive,microbial inhabitants have learned to adapt by varying all of the following EXCEPT:

These are enzymes that cut the bacterial DNA at specific locations.

The function of a cell wall is to:

All the following are types of media EXCEPT:

These bacteria cannot grow in the presence of oxygen.

Name the numerous short projections that extend from the cell surface and are used for locomotion.

A microbiology technologist performs a traditional bacterial stain on a colony from a wound culture that is suspected to contain bacteria from the genus Clostridium.The unstained areas in the bacterial cell observed by the technologist are called:

This type of chromosomal DNA is found in eukaryotic cells.

Diagnostic schemes in the microbiology laboratory typically analyze each unknown bacterium's metabolic processes for all the following EXCEPT:

What is the purpose of a capsule?

When performing a Gram stain on a gram-negative organism,the crystal violet is absorbed into this outer cell wall layer then washed away with the acid alcohol.What is the main component of the outer layer of the cell wall?

Diagnostic microbiologists emphasize placement and naming of bacterial species into all the following categories EXCEPT:
