What's the difference of virus lytic cycle and replication cycle?

The lytic cycle begins when the virus attaches its tail fibers onto the surface of a bacterium, and injects its DNA into the cell. There is only a chance that the virus will come in contact with the right type of the host cell. In most cases, the virus will not completely enter the cell at all, but rather just their DNA. This process is known as infection as the virus is infecting the host cell.

The next process, growth, is when the entered DNA takes action. Because the host cell cannot differentiate between the proteins of itself and the virus, the virus DNA tricks the host cells to start making and replicating their DNA instead while they start wrecking the host cell, and shutting it down.

When enough of the virus has been replicated through the host cell, the virus will take over to a further step by using the materials of the host cell to make thousands of copies of its own. In no time, the host cell will be filled with copies of the virus; however, depending on the virus, the time length varies. Some virus only takes minutes to reach this stage while others may take hours.

For the last stage of this cycle, the infected host cell will burst and spread thousands of viruses into the body as there are too many viruses in the cell. As the virus flows around in our bloodstream for example, they will attach to other host cells, and start the whole cycle all over again reproducing thousands and thousands of them that infects our bodies, and cause flu and other diseases. Of course, our body is also designed to strike back from these viruses!

A replication cycle refers to the reproduction cycle of viruses. A replication cycle begins with the infection of a host cell and ends with the release of mature progeny virus particles.

Virus lytic cycle is the group of events that take place when virus enters the host i.e. bacteria, human etc and replicate, and produce copies of its own genetic material and kills the host cell by lysis.

so simply we can say that viral replication is one of the step within the lytic cycle of virus. Virus can also undergoes lysogenic cycle in which replication do occur but lysis does not occur, usually the virus prefers lysogenic cycle.

Replication is formation of new copies of the genetic materia i.e. DNA, as a result of replication one DNA give rise to its daughter DNA or we can simply say that one DNA forms two DNA having the same sequence of base pairs

well a replication cycleis one in which the virus multiplies into two...i mean the dna/ rna replicates once...in a lytic cycles the virus multiplies by making many copies of the dna and which are assembled into the new viruses and which are finally released from the host cell after killing the host cell....a replication cycle can occur without causing lysis of the host cell...

Excellent than others

After trying out for all antispyware software’s available in market I finally switched on to
