Summary Introduction

Introduction:

The chromosomes are formed by the packing of the DNA (deoxyribonucleic acid) onto the protein molecules. The packing of the DNA condenses its length and allows it to fit into the nucleus. Most of the sexually reproducing organisms are diploid that is they have two sets of chromosomes in a cell.
