Study Notes
Basic Taxonomic Unit
- The basic taxonomic unit in microbiology is the species, typically defined by genetic similarities and characteristics of organisms.
Distinctive Feature of Prokaryotic Cells
- Prokaryotic cells lack a membrane-bound nucleus, distinguishing them from eukaryotic cells. Instead, their genetic material is located in a nucleoid region.
Lifespan of Bacterial Spores
- Bacterial spores can survive in the environment for extended periods, ranging from years to decades, due to their highly resistant structure.
Function of Ribosomes
- Ribosomes are primarily responsible for protein synthesis in a cell, translating messenger RNA (mRNA) into amino acid sequences.
Bacterial Organelles for Adhesion and Conjugation
- Pili and fimbriae are the bacterial organelles involved in adhesion to surfaces and other cells. Conjugation is facilitated by specialized pili called sex pili.
