sYaKuuRiolAKU nchImb According to recent reasearch, Nepalese have different types of Allele. Each ethnic groups of Nepal contains four out of five DNA's amino acids which are AGCTU. A for Adenine G for Guanine C for Cytosine T for Thymine U for Urasil So, same group often have similar amino acid conformation but if these people do not segregate and wants to bind then their DNA structure gets in conflict, as a result 'mutant' will form.
