A virus is a self-replicating life form that attacks and destroys all living matter. Since they need living matter in order to reproduce and survive, a virus has the curious ability to take over certain types of cells. The viruses then spread throughout the human body, causing disease when their hosts are healthy and unwell. For this reason, most viruses cannot be killed by antibiotics. As well as this, since they rely on living matter to continue to reproduce, a virus is very difficult to destroy once it has infected a cell.
Because viruses are so important to the health of a cell, it is vital to kill a virus before it damages the cell. Viruses depend on the living cells of another organisms for their own survival and reproduction, as they can only capture or store energy in a cell if they can penetrate the host cell. Therefore, they are generally regarded as living things, but since they cannot actively function without a host cell, they are actually often looked upon with distrust and fear. Since a virus can replicate itself by taking up residence in an infected host cell, there is always a risk that it will start a new colony within the same cell and infect the host again.
Since the process of viral multiplication requires the introduction of genetic material contained within the virus, it is often assumed that the virus is responsible for the creation of all living organisms. However, this is not strictly true as it is possible for the genetic material contained within a virus to be introduced into the host cell’s cellular Membrane. Once the genetic material is introduced, the infected cells will replicate rapidly, thereby replacing all the foreign genetic material with the native genetic material. This scenario also plays a significant role in the spread of the HIV virus.
Some viruses can generate a protein by releasing it into a host cell. This infectious protein is generally believed to be responsible for the replication of the viruses. Some of the known examples of these proteins are retroviruses, envelopes and insect virulence genes.
The immune system of most humans is generally very effective in fighting against most common viruses, however they can sometimes be weakened due to other causes. These causes include a decrease in the number of T-cells or White Blood Cells in the body, increased toxicity of some microorganisms, and exposure to various toxins. The weakening of the immunity of the body can affect the capacity of the individual to fight off infections and can even result in the death of their body. This is why a number of viruses have the ability to cause a weakened immunity in humans.
There are also viruses that use nucleic acid in their viral codes to activate the transcription factor that is responsible for initiating transcription. The transcription factor is necessary in order for the RNA virus to initiate communication between cells within the body. However, once the transcription factor is affected by the nucleic acid, the virus is unable to carry out this task, effectively crippling the functioning of the organism. A major component of many viruses is DNA, which encodes the genetic instructions necessary for the virus to function. Most viruses use a nucleic acid construct called a transposon to insert genetic material either inside the genes of the living organisms or on different cells throughout the body. Although the majority of viruses are slow acting and rarely attack living organisms, some of them are capable of causing severe health complications and disease when they insert their genetic material on vital cell surfaces.
