In this article we will discuss about the life cycle of phage M13. M13 uses the F pilus of E. coli to infect the cell. Protein pill located on the tip of M13 contacts the TolA protein located on the pilus of host cell. This interaction causes a conformational change in pVIlI from 100% alpha-helix to 85% alpha-helix resulting in [...]
In this article we will discuss about the two examples of mycoviruses: 1. Mycoviruses of Mushrooms 2. Mycoviruses in Plant Patliogenic Fungi. 1. Mycoviruses of Mushrooms: At least six viruses and VLP have been reported from the cultivated mushrooms, A.bisporus nearly from all countries where it is grown widely. The mycoviruses occur in a mixture of cells and are extremely [...]
Lambda consists of two types of life cycles, the lytic and lysogenic. Lytic Cycle: The events of lytic cycle, starting with adsorption, at 37°C occurs as below: Time (t) = 0 minutes: Phage adsorbed and DNA is injected = 3 minutes: First early mRNA is synthesized = 5 minutes: Two classes of early mRNA are synthesized = 6 minutes: DNA [...]
