Answer:
True
Explanation:
Polymorphism is a phenomenon that arises when proteins, DNA and RNA can appear with different molecular forms. Polymorphism is characterized as single nucleotide polymorphism when molecular variation occurred in only one nitrogenous DNA base, thus causing genetic variation in a population. This type of polymorphism is very important to regulate the gene expression of individuals and to measure the progression of a disease. This requires that the unique nucleotide polymorphism be identified. This identification occurs through biochemical, evolutionary and genetic evidence.
