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 [...]
In this article we will discuss about the replication of ssDNA phage. I. Adsorption: The cell wall surface of E.coli contains specific receptor sites. For example, the receptor site of ØX114 present on outer membrane of cell wall of Salmonella typhimurium is a lipopolysaccharide. The phage gets adsorbed on bacterial cell surface through any one of 12 icosahedral vertices. The [...]
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 [...]
