  • Below are the answer and explanations.

DNA restriction fragment length polymorphism

DNA restriction fragment length polymorphism (DNA RFLP) is a pair of variants that can occur in an average of about 200 base pairs in the genome. This results in differences in nucleotide sequences between individuals and is called DNA polymorphism.

Many DNA polymorphisms occur at restriction endonuclease recognition sites. The enzymes decipher the DNA fragments to produce fragments of different lengths, called restriction fragment length diversity.

This polymorphic fragment can be used as a genetic marker to determine whether a family member or fetus is a carrier of an oncogenic gene.

With the increasing understanding of genes, it has been found that among different individuals of the same species. Although the structure and function of their protein products are identical or differ only slightly.

However, there are differences at the DNA level, especially in regions that do not encode proteins and in regions that do not have important regulatory functions. Such DNA mutations that do not affect the phenotype of the organism are called neutral mutations.

Because neutral mutations in DNA are often passed on to the next generation in a Mendelian dominant manner. Therefore, testing for such mutations has been widely used for the diagnosis of genetic diseases, prenatal diagnosis, paternity testing, and identification of criminals in forensic medicine.
