Study Notes
DNA Polymerase Correction Mechanism
- DNA Polymerase has the ability to correct base substitutions and prevent misincorporation of nucleotides through its proofreading and editing activity
- This mechanism ensures high fidelity of DNA replication and repair
Bacterial Growth and Culture
- Vibrio cholerae can grow in a medium with a pH of 8.5
- Treponema pallidum requires a specific medium for growth, which is Serum Broth
- Fastidious organisms need Enriched medium to grow
- Bacteria have a tendency to stain more readily with cationic (positively charged) dyes due to the presence of large amounts of acidic substances
- A distinct characteristic of many Pseudomonas isolates that aids in identification is the production of a fecal odor
