How to draw a virus

The drawings of the virus are as follows:

1. First, let's draw a circle. You can draw it with the help of a circular tool.

2. Then in the circle, we draw the five senses, two big eyes and a big mouth, which look terrible.

3. Draw some small triangles around the circle, and you can draw a simple virus.

4, the following can be painted! Let's paint the virus and the triangle around it orange and the mouth pink, and the simple virus stick figure will be finished!

virus

Virus is a small and simple structure, containing only one kind of nucleic acid (DNA or RNA), which must be parasitic in living cells and reproduce through replication. Viruses can be divided into plant viruses, animal viruses and bacterial viruses, and can also be divided into single-stranded RNA viruses, double-stranded RNA viruses, single-stranded DNA viruses and double-stranded DNA viruses in structure.

Virus is a cell-free life form, which consists of a long nucleic acid chain and a protein shell. Viruses do not have their own metabolic mechanism and enzyme system. So when the virus leaves the host cell, it becomes a chemical substance that has no life activity and cannot reproduce on its own.

Its ability of replication, transcription and translation is carried out in the host cell. When it enters the host cell, it can use the substance and energy in the cell to complete its life activities, and according to the genetic information contained in its own nucleic acid, it can produce a new generation of viruses like it.
