Introduction Deoxyribonucleic acid (DNA) is a long linear polymer located in the nucleus of a cell. It is developed from nucleotides and shaped like a double helix. It is related to the transmission of hereditary information from one generation to the second generation. DNA contains the information for the development as well as reproduction of an organism, thereby leading to a normal life. In the year 1953, James Watson, a biologist, and Francis Crick, a physicist, discovered the structure of DNA in a laboratory in England (LEROY, 2003). The structure of DNA helped scientists to know the process ...

Introduction

Taxicab geometry is a better idealized model for urban geography as compared to Euclidean geometry. This is very applicable in urban planning where distances within the roads are divided within rigid blocks and the shortest distance cannot be the hypotenuse. This is very helpful in establishing the shortest distance between any two points. ( Surhome, Timpledon & Susan). Geometry can be traced back over 2000 years. This is solely refers to Euclidean geometry introduced by Euclid. A German mathematician Hermann Miknowski proposed taxicab geometry. He had the proposition that distances in taxicab geometry is different than in Euclidean geometry. His ...
