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 [...]
In this article we will discuss about the structure of RNA. The RNA is usually single stranded except some viruses such as TMV, yellow mosaic virus, influenza virus, foot and mouth disease virus, reovirus, wound tumour virus, etc. which have dsRNA. The single strand of the RNA is folded either at certain regions or entirely to form hairpin-shaped structure. In [...]
