Explore prokaryotic strategies in laboratory diagnostics through this engaging quiz. It covers bacterial defense mechanisms, staining techniques, and differences in ribosomal structures. Essential for students and professionals in microbiology, enhancing understanding of bacterial behavior and diagnostic procedures.
The structures of the ribonucleotides it is composed of.
The strand that is transcribed to create the rRNA component
The sizes and number of the rRNA components.
Prokaryotic ribosomes are comprised of only rRNA and no protein
Rate this question:
Gram positive
Gram negative
Mixed
No staining
Rate this question:
It dissolves lipids, allowing the crystal violet to wash out of Gram negative cells
It counterstains the decoiorized cells, allowing them to be visualized
It fixes the crystal violet to the peptidoglycan of Gram positive cells
It complexes with the crystal violet, creating larger molecules.
Rate this question:
B cell-mediated antigen presentation to naive CD4-' cells

Rate this question:
Peptidoglycan irreversibly binds to the appkation of crystal violet after the application of safranin.
The outer membrane irreversibly binds to the application of crystal violet after the application of ethanol or acid ethanol.
Peptidoglycan irreversibly binds to the application of crystal violet after the application of the mordant (iodine.)
The inner membrane irreversibly binds to safranin following safranin application followed by rinsrig.
The very thin layer of peptidoglycan in the cell wall irreversibly binds to the application of crystal violet after the application of the mordant (iodine.)
Rate this question:
MHC class II molecules present antigen mainly to CD8+ T cells
MHC class II molecules are found mostly on B cells, dendritic cells, and macrophages
