Answer to Question #23415 in Microbiology for Kim malinowski
1) What are three reasons a diplococci couldn't have an axial filament?
2)Streptomycin is an antibiotic that bind the 30S subunit of the prokaryotic ribosome. Streptomycin is a large molecule that has many portential charges on it. How could this molecule get to a bacterium's ribosomes?
Penetrates the bacterial cell by active transport and passive diffusion, which is enhanced by means that violate the synthesis of cell membranes (such as penicillin). Irreversibly binds to specific receptor proteins in the 30S subunit of the ribosome. Violated initiation complex formation between RNA and 30S ribosomal subunit. As a result, defects occur when reading data from a matrix (information) RNA synthesized defective proteins. Polyribosomes break up and lose the ability to synthesize protein, damaged cytoplasmic membrane and the cell dies.
