Genes remain on DNA (De-oxy-ribonucleic Acid). Gene consists genetic code made of three bases out of four bases ACGU which are called nucleotides or triplet like ACG, GGU, GUA. Genetic science has searched out all number of genes, base pairs and diseases associated with each chromosome as follow[37]:
