In this article we will discuss about the mechanisms of chemo-taxis. The special proteins called chemoreceptors are supposed to be present in the periplasmic space of plasma membrane that detects the attractants and repellents. These proteins bind to chemicals and transmit signals to the other components of chemo sensing system. So far about 20 chemoreceptors for attractants and 10 for [...]
The following points highlight the nine main types of plasmids in bacterial cytoplasm. The types are: 1. Sex Factor 2. R (resistance) Plasmids 3. Heavy-Metal Resistance Plasmids 4. Col Plasmids 5. Degradative Plasmids 6. Penicillinase Plasmid of Staphylococcus Aureus 7. Cryptic Plasmids 8. Ti-Plasmids of Agrobacterium Tumifaciens 9. Ri-Plasmids. Type # 1. Sex Factor or Fertility (F) Factor: The plasmids [...]
The following points highlight the six main components of cytoplasm of bacteria. The components are: 1. Ribosomes 2. Molecular Chaperones 3. Nucleoids 4. Plasmids 5. Cytoplasmic Inclusions 6. Spore and Cysts. Component # 1. Ribosomes: All living cells contain ribosomes which act as a site of protein synthesis. High number of ribosomes represents high rate of protein synthesis and vice [...]
