More is the genetic diversity more is the variation in the traits. This genetic variation can be utilized to determine the sequence information of an individual. Utilization ... Read More

Introduction The generalization made by Theodosius has been validated by recent progress in the field of molecular biology and biochemistry. All modern organisms have been derived from common ancestor by a series of small changes, each change is attributed a selective advantage over the other, this is strongly supported by ... Read More

Introduction Chromosomes are thin fibre like structure that forms the most important part of the genetic material and is mostly confined inside the nucleus in eukaryotic cells. During cell division chromatin condense to form rod like structures containing centromere and chromatids. Chromosomes are composed of DNA, histone proteins and non-histone ... Read More
