It forms a contractile ring at the septum => Made up of FtsZ (tubulin homologues) molecules important for bacterial septation B. It controls the replication of DNA => Replisome contains DNA replication machinery C. It separates the newly synthesized DNA molecules => ParA polymerizes/depolymerizes to attach...

WGU Microbiology C453 Objective Assessment Study Guide What is the role of the capsule in some bacterial cells? ️️ The capsule protects bacteria from phagocytosis and helps them adhere to surfaces. How do flagella contribute to bacterial survival? ️️ Flagella allow bacteria to move toward favorable environments and away from hostile ones, enhancing survival. What is the importance of aseptic technique in microbiology labs? ️️ Aseptic technique prevents contaminati...

WGU Clinical Microbiology Final Exam Rated A+ Describe the role of restriction enzymes in bacteria. ️️ Restriction enzymes cut DNA at specific sequences, helping bacteria defend against invading viral DNA by degrading foreign genetic material. What is a facultative anaerobe, and how does it adapt to varying oxygen levels? ️️ A facultative anaerobe can grow with or without oxygen, using aerobic respiration when oxygen is available and switching to anaerobic respiration or ferm...
