How does antibiotic resistance develop?
What is overuse of the antibiotic, not completing the course of the antibiotic prescription, bacteria with resistance to the antibiotic, and antibiotic resistant bacteria reproduce and pass on the resistant gene to their offspring
A substance derived from a living organism that is capable of killing or inhibiting the growth of a microorganism
What is an antibiotic?
The ability of bacteria or fungi to grow in the presence of an antibiotic that would normally slow their growth or kill them; antibiotic resistance arises by mutation and becomes widespread when antibiotics are overused

The complete breakage of the transmission cycle of a pathogen so that there are no more cases of the disease caused by the pathogen anywhere in the world
What is disease eradication?
The transfer of a pathogen from a person infected with that pathogen to an uninfected person; transmission may occur by direct contact, through the air or water or by animal vectors, such as insects
What is disease transmission?
Disease is cholera, name the causative agent and pathogen.

Rifampicin is one of the antibiotics used to treat TB. Rifampicin inhibits RNA polymerase in bacterial cells by binding to a site other than the active site. This prevents polypeptide synthesis. Suggest and explain how rifampicin prevents polypeptide synthesis in bacterial cells
What is changes the tertiary structure of active site which is no longer complementary to RNA, rna not synthesis, transcription does not and translation prevented
Preventing TB and treatingTB
