CONTENTS DNA, RNA AND PROTEIN SYNTHESIS DNA
... DNA biosynthesis proceeds in the 5′- to 3′-direction. This makes it impossible for DNA polymerases to synthesize both strands simultaneously. A portion of the double helix must first unwind, and this is mediated by helicase enzymes. The leading strand is synthesized continuously but the opposite str ...
