Biology - Molecular Basis of Inheritance Question with Solution | TestHub

DNA polymerase catalyzes the polymerization of deoxynucleotides only in one direction, which is $5^{\prime }\to 3^{\prime }$.

Therefore, during DNA replication, the formation of the new strand always takes place in the $5^{\prime }\to 3^{\prime }$ direction on both the leading and lagging templates.

On the leading strand, the synthesis is continuous, while on the lagging strand, it is discontinuous (forming Okazaki fragments), but the direction of synthesis remains $5^{\prime }\to 3^{\prime }$ for both.

Answer: in $5^{\prime }\to 3^{\prime }$ direction on the both the templates.
