Biology and Information Technology both are different fields but if these fields will work for each other surely some hidden and fruitful results will come out. Bioinformatics is the science of managing, mining, and interpreting information from biological sequences and structures.In these fields more work is yet to be done . By this book I want to introduce that by analyzing protein sequences of human being we can find out that a person is suffering from which disease or not suffering. You can get more information about different algorithms which are very useful for analyzing Biological Data and give significant results. Transcription and Translation algorithms Which I have introduced in this book are very useful for converting DNA to RNA and finally to Protein sequences. Surely you will get some new concepts by this book which can be used for enhancing and promoting the research work in Bioinformatics .So read it and analyze it.
