WebSome people think that in the leading strand, DNA is synthesized in the 5’ to 3’ direction, while in lagging strand, DNA is synthesized in the 3’ to 5’ direction. This is not the case. DNA polymerase only synthesizes DNA in the 5’ to 3’ direction only. WebThe DNA strands have the opposite orientation: one strand is in the 5′ to 3′ direction with respect to the carbon atoms on the sugar (deoxyribose) and the complementary strand is in the 3′ to 5′ direction ( Figure 1 ( a )).
