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....

General Characteristics of Mutation

There are certain characteristics set in mutation. This helps to draw the general properties of the mutation process. The mutation is a large process that is going on in small steps day by day. So, there will be some characteristics of this process. Mutations that are happening to the body are generally recessive in order. But dominant mutation can also be possible. But the rate is very low. This means, the recessive character often comes to nature due to the mutation process. The mutation process generally leads to fatal traits for an organism. This means the mutation process often creates harmful changes. But sometimes a change can be used for the organism’s benefit. The mutation process generally occurs randomly. This means the mutation process can be witnessed at any position in the gene. That position will be chosen randomly. The mutation process generally occurs in a repeated format. This means, if a mutation happens to any gene, then there will be a chance of happening mutation again. So, the mutation process is recurrent. The mutation process generally leads to the creation of other genes from any mutated genes. So, it is observed that the mutation process shows the pleiotropy process in the genes....

Role of Mutation

Scientists often believe that the mutation process occurs in the body for the creation of any harmful process. And eventually, that process will lead to death for any individual. This statement is moreover true. Mutation plays a role in the creation of any harmful process. Many times, mutation of any certain gene is the reason for any special disease. But that doesn’t mean any individual is going to be dead. The mutation sometimes appears as a boon to survive in nature....

Classification and types of Mutation

Spontaneous Mutation: It is a special type of mutation. In this case, the mutation is happening in the body, without any external factor. This means the mutation is started in the body due to some internal factor. In this case, the mutation process is known as Spontaneous Mutation. This mutation process is linked to the internal factors that cause mutation. Like here, the DNA replication process will cause Spontaneous Mutation. Spontaneous means anything that can happen without any agent. So, form that way, the name of this mutation process is appropriate. Induced Mutation: This is the opposite of the Spontaneous Mutation process. In this case, the mutation is not happening in the body automatically. Rather, there is a need to induce any special agent in the body that might cause the mutation process. In this case, the agents are known as the Mutagens. This mutation process is completely linked to External causes. Here, the UV Rays will be a mutagen. In presence of these agents, the DNA will break down or make some changes. That will cause the mutation process. As the agents need to be induced or inserted into the body, so from that purpose the name is appropriate....

Importance of Mutation

Mutation is a very important step in the human body. Oftentimes, the mutation is considered a fatal change in the body. And this is quite true in maximum times. But still, there is some importance is present in the mutation process. Like the mutation is important for the evolution process. The mutations that are going in the body, means those are spontaneous mutation, which helps a lot in the evolution process. These mutations help to gain some important new features for the body. And this mutation helps to survive in nature. As a result, the features or traits that are occurring in the body will be transferred to the next generation. As mutation always happens to the genetic structure. So, a mutation that might be fatal helps to shape the generations to survive in nature....

Molecular Basis of Gene Mutation

The mutation is a process that can’t be seen from the outside of the body. This process is happening in the cellular structure of the body. More preciously, this process is going on inside the genetic structure of the cell. Genes are very small elements in the human body. Mutation occurs there inside any gene. Often genes are termed as a molecule of the body. As they are so tiny like any molecule. That is the reason; the mutation often has a relation with the molecular base....

Effects of Mutation Process

The effects of the mutation process are unbelievable. There are a lot of effects are present in the mutation process. The mutation process might sometimes cause a benefit for the organization. Or sometimes it causes problems for the organisms. So, depending upon their effect on the human body, the mutation process can be divided into two categories. One will be the beneficiary effect and another will be the fatal effect....
