Genetic mutation
The process through which alters the DNA sequences making up the gene is a gene mutation. The mutation differs from one person to the other in respect to size and from a single DNA building block to a more extensive section of a chromosome that multiples the genes. It mainly happens due to environmental factors, UV light, and cigarette intake, which in return, dislocates the DNA.
There are two significant classifications of gene mutation, namely, hereditary and somatic mutation process. The hereditary, also known as germline mutations, are taken from the parents and is present in everybody of the person. They are present in the parents’ eggs or sperms, and when they fertilize an egg forms having both the mother’s and father’s cell DNA. It, therefore, means that the offspring will have both the mutation of each parent cells.
Somatic, also is known as an acquired mutation, can occur to some specific persons since they happen on different cells as people grow. It happens due to the changes in the environmental factors, especially ultraviolet radiation from the sunlight rays or during the cell division that dislocates the DNA. It is a type of genetic mutation that can be transferred from one generation to the other.
Evolution plays some part in gene mutation since as population and organisms change, through the process, the genes can vary as a result of protein alteration. Some changes may be advantageous to the microorganisms, which means that they adapt the different living styles as long as they can survive and are in a position to reproduce. The variation can thus be passed on to the coming generation, and over time, the same character trait permanently turns to a healthy and, therefore, the gene mutation.
Mutation thus occurs in different forms and can come along with both benefits and disadvantages. Some of the benefits include the survival of organisms and diversity development. Through mutation, humans are now in a position to adapt to environmental changes. For instance, it is with the help of modification that antibiotics are in apposition to resist bacterial infection, sickle cell causing malaria, strong immunity for the people with a disease such as HIV and diabetes, among others.
The other benefit we acquire from the gene mutation is the diversity or uniqueness, and the change may dislocate some of the physical features to better ones. For example, research says that we once had brown eyes, but with the help of gene mutation, the OCA2 gene was disrupted, resulting in a change that stopped the creation of brown eyes. The other factor present as a result of gene mutation maybe; freckles, beauty spots, hair colors, and baldness.
My position about the significance of the gene mutation in human evaluation goes alongside the fact that it is through gene mutation that people are in apposition to deal with some significant diseases like diabetes and HIV and Aids. It helps the human lineage and saves people from deadly diseases with no cure. The other factor about inheritance due to gene mutation impresses me because some people may be lucky enough and get attractive like skin color and brain capacity feature coming up naturally.
Although some changes may be beneficial to humankind, some people may be unlucky acquire some diseases such as asthma, cancer, and heart problems as a result of gene mutation. The other danger that comes along with the gene mutation is a genetic disorder that may cause an abnormality of the DNA of some individuals. An example is the non-disjunction disorder highly known to be as a result and causes growth delays, and it is as a result of mutation.
