The following points highlight the seven important enzymes involved in the process of DNA replication of prokaryotes. The enzymes are: 1. DNA Polymerase 2. Primase 3. Polynucleotide Ligase 4. Endonucleases 5. Pilot Proteins 6. Helicase 7. Single-Strand Binding (SSB) Protein. Enzyme # 1. DNA Polymerase: DNA polymerase is the chief enzyme of DNA replication. DNA polymerase activity was discovered by [...]
The following points highlight the three main phases of DNA replication in prokaryotes. The phases are: 1. Initiation 2. Elongation 3. Termination. Phase # 1. Replication Initiation: Replication initiation involves the following events: (1) Recognition of origin, (2) DNA melting, i.e., separation of the two strands in the origin region, (3) Stabilization of the single strands, (4) Assembly of primosome [...]
In this article we will discuss about the position of prokaryotes in the living world. Traditionally, the living organisms were placed in two kingdoms, the plants (Plantae) and the animals (Animalia). Leeuwenhoek's discovery of microorganisms and the gradual discovery of large number of diverse microorganisms made it impending to think about creating a third kingdom to accommodate those organisms, because [...]
