الطفرات الوراثية و طرق الإصلاح بواسطة ال (DNA)‎ : دراسة تحليلية

الملخص EN

The purpose of the research is to identify the mutations, their causes, types, effects and mechanisms of transmission to the gene, as well as the probability of occurrence of the mutation and its necessities.

The aim of the research is to demonstrate the methods of repair of mutations through DNA and the factors that lead to DNA damage and the mechanisms of reform.

The problem of research has been focused on the fact that many chemicals have the ability to make genetic mutations or chromosomal changes.

In recent years, the effects of dozens of substances that have the potential to induce chromosomal changes if exposed to cell or tissue, Dah and a certain period of time.

The research suggested that the attempt to identify genetic mutations would help in the repair of genetic problems through the repair of DNA, which helps to avoid many of the deformities and genetic diseases, and the research has reached a number of results, the most important of which is the following: 1- It is possible to inherit a mutation from our parents, and new mutations can occur in our cells that did not exist in our parents because they simply occurred after our creation began or created us.

Thus mutations may be inherited (from one parent) or not inherited.

2- The mutation may affect the gene in reverse.

Instead of decreasing the amount produced by the mutant gene, the opposite occurs and the amount produced and allowed within the cell increases.

This increase in a pattern harms the cell and the disease occurs.
