Today in biotechnology large number of research is going on and most of them basically related with improving any variety of plant or animal by inserting a foreign gene with economically important characteristics but sometimes it can be improve by increase gene product or making product storage to a particular body part or product . All such things can be done only if we use a specific DNA sequence called promoter. In simple words promoter is as important as clutch during starting a bike along with kick. Promoter can be located near or within the coding region and help in initiating transcription, determining the level and place of gene where it is going to express. This book provide a vast knowledge of promoter under simple and short topics specially related to promoter role in transcription, promoter types and regulation of promoter by various factors along with evolutionary importance of promoter.

The 21th century has been called century of biotechnology. It is the field at the cutting edge of science. The exponential increase in the quantity of scientific information and the rate, at which new discoveries were made, requires very elaborate, interdisciplinary and update information and their understanding. DNA Sequencing and Gene Cloning - An introduction covers various topics related with DNA sequencing and amplification in vivo and in vitro, updated knowledge of types of DNA sequencing and their applications. In Gene Cloning section it contain all aspects related to it including how gene cloning is important and at which step it is important in molecular project. This book also contains some mathematical conversions which are important for a biology lab. So that this book is very fruitful to all students who like to get information about sequencing and DNA amplification in vitro and in vivo environment.
