Virus is found everywhere we go. Viral diseases have plagued the lives of millions of people for decades now. From viral fever to viral infections, they are nasty and, once they enter the human body, hard to get rid of. So how do virus function exactly? The answer to this question is reproduction. Their main function is to reproduce, or in their case, multiply into a thousand viral cells and spread themselves inside the human body.
Viruses are the deadliest kind of foreign bodies that can harm our body. They are much more lethal than bacterial and fungal diseases, and multiply more rapidly than them. Viruses don’t even need particular weather conditions to multiply, all they need is a host body. So, stopping a virus reproduction is much more difficult than preventing bacterial or fungal reproduction. So the more we know about these processes, the better. The first thing that we need to know is that there are two kinds of cycles in virus reproduction, which are called the Lytic cycle and the Lysogenic cycle. In this article, we are going to have a thorough look at the two cycles.
In this cycle of virus reproduction, the virus infuses the human host cell with its nucleic acid. This enables the virus to reproduce using the host cell’s protein coat, eventually overwhelming the host cell, causing it to burst. The reproduced virus cells then move on to other fresh host cells, and the entire process repeats again. This cycle is generally followed by the virus of viral fevers and infections.
This cycle of virus reproduction is utilized by virus which are slow to multiply, like the HIV virus and the herpes virus. In this cycle, the nucleic acid of the virus cell does not immediately attack the host cell, instead takes its time to develop hold on the host cell. This is because the nuclei acid of the virus is not active. However, when it does take hold of the host cell, it multiplies soon enough and destroys the host cell in the process, moving on to other host cells.
Following is a picture of the various virus reproduction techniques. The picture clearly shows how the viruses divide and multiply amongst themselves to take complete control of the human cell.
