Question

_______ injects material cell, which inhibits bacterial DNA, RNA and protein synthesis. Host DNA is

degraded

Answer 1

Dactinomycin inhibits bacterial nucleic acid and protein synthesis, while pathogen-produced nucleases degrade extracellular DNA. These inhibitors do not target host cells.

Step-by-step explanation:

Dactinomycin (Actinomycin D) is an antibiotic that inhibits bacterial DNA, RNA, and protein synthesis. It binds to double-stranded DNA and interferes with the movement of the RNA polymerase enzyme. In addition, pathogen-produced nucleases degrade extracellular DNA, which can trap bacteria and prevent their spread. This degradation allows bacteria like S. aureus to escape and spread to adjacent tissues.

However, it's important to note that these inhibitors of bacterial nucleic acid and protein synthesis do not target host cells due to differences in the structure and function of bacterial and host cell components.
