A most common and important source of genetic variability is known to be present uniformly throughout the genome is termed Single Nucleotide Polymorphisms or SNPs. Interest in SNPs lies in the fact that these polymorphisms may be responsible for the differences in disease susceptibility, drug metabolism and response to environmental factors between individuals. Even, if they are not directly responsible for the disease, they serve as genetic markers for a nearby locus that might be responsible.

Why Nature Preferred DNA over RNA?
We all know that DNA acts as a genetic material in most of the organisms on this planet earth. However, it is also clear that RNA also acts a genetic material, but only in some viruses. During the evolution, nature has considered DNA over RNA as genetic material, because DNA is more stable and more efficient than RNA.
Who discovered that DNA is the Genetic Material?
The discovery of DNA as the genetic material was one of the major achievements of science in the 20th century. This discovery made DNA, the chemical basis of heredity. It took almost 80 years for scientists to prove that DNA is the genetic material. Early works: In 1869, Johann Friedrich Miescher, a young Swiss medical student, discovered… Continue reading Who discovered that DNA is the Genetic Material?
