i read it in the book, its called the anti sense strand, which acts as a template for the coding of the mRNA. By the way,wats the enzyme called for DNA synthesis ? DNA Polymerase or DNA Ligase or DNA Helicase, cause i read about this some where which says that any of these three can b written :S ???
