In this article we will discuss about:- 1. Experimental Proof of Replication of DNA 2. Enzymes for DNA Replication 3. Process of Replication of DNA. In addition to the double helical structure of DNA, Watson and Crick also proposed a scheme for DNA replication. According to this scheme, the two strands of double-helix would separate and act as a template [...]
The following points highlight the six main stages involved in the replication of animal viruses. The stages are: 1. Adsorption 2. Penetration 3. Un-Coating 4. Replication of Viral Genome 5. Synthesis and Assembly of Virus Capsids 6. Release of New Virus. Stage # 1. Adsorption: Adsorption to the host cell surface is the first step in reproduction cycle of animal [...]
In this article we will discuss about the replication of virus by lytic and lysogenic cycle. Replication of Virus by Lytic Cycle: This type of cycle is seen in T-even phages (T2, T4 etc.) which attack Escherichia coli. The lytic cycle consists of five steps (Fig. 2.45): (a) Adsorption, (b) Infection (Fig. 2.44), (c) Synthesis of phage components in host [...]
