Causes of Mutation
The mutation is the process that is being controlled by some causes. It is prompted out in the body’s DNA due to some causes. These causes can be divided not two categories. Depending upon the cause from where it is arising, the mutation can be two types.
- Internal Mutation: This is the mutation type that can be observed most of the time. DNAs need to split into two parts. As they also need to increase their number. During the process of cell division, the DNA of one single cell divides into two parts. One DNA set belongs to one cell. On the other hand, another DNA set will belong to a newly formed cell. During this splitting or the replication process, the genomic sequences get changed. As a result, there will be a mutation in that DNA. Normally, these mutations are required for the evolution process.
- External Mutation: This is a very rare type of mutation process. In this process, there is no role in the DNA replication process. Rather than, some chemicals or agents inserted into the human body from the outside. And they started reacting on the DNA sequences. Like the UV Rays. The UV Rays are inserted into the body. And then they start acting upon some DNA bases. This causes the breaking of the DNA from the unexpected region. The UV Rays act upon the Thymine base in the DNA. As a result, the DNA sequences are changed. And mutation can be seen there.
Mutation
The human body might be visualized as a simple organism. But it is the combination of different complex processes. From the outside, a human body might resemble a very simple one. A body that has two arms, two legs & one head for monitoring purposes. But from the inside of the body, there are many surprises still present for scientists. One of the major surprises was the Genetic Sequence of humans. This is still a field where scientists are working to find out some important details. Genes or DNA are the micro-controlling areas in the human body. They are most important than the brain. As the brain is also functioning with the help of DNA & its sequences. Any changes in this structure might be fatal for the body. Mutation is one type of change in DNA.
