Abstract DNA sequencing process utilizes biochemical methods in order to determine the correct order of nucleotide bases in a DNA macromolecule using sequencing machines. Ten years ago, sequencing was based on a single type of sequencing that is Sanger sequencing. In 2005, Next Generation Sequencing Technologies emerged and changed the view of the analysis and understanding of living beings. Over the last decade, considerable progress has been made on new sequencing machines. In this paper, we present a non-exhaustive overview of the sequencing technologies by beginning with the first methods history used by the commonly used NGS platforms until today.
