Analysis of Chromosome A chromosome is an organized structure of DNA and protein found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. Chromosomal DNA encodes most or all of an organism’s genetic information; some species also contain plasmids or other extrachromosomal genetic elements. Chromosomes vary widely between different organisms. Although red blood cells do not contain chromosomes, white cells do. Typically, eukaryotic cells have large linear chromosomes and prokaryotic cells have smaller circular chromosomes, although there are many exceptions to this rule. Chromosomes are the essential unit for cellular division and must be replicated, divided, and passed successfully to their daughter cells so as to ensure the genetic diversity and survival of their progeny. Chromosomes may exist as either duplicated or unduplicated. The book provides an easy guidance to difficult subject. Analysis techniques explained in an easy to follow step-by-step format makes this book highly useful to the students, teachers and researchers in the field.
