All of the following involve molecular biology techniques except ligating dna fragments together. using a dna polymerase to copy dna via pcr. creation of okazaki fragments. using restriction enzymes to cut specific sequences of dna.

The correct answer is-creation of Okazaki fragments

Explanation:

Molecular technique is the methods that are used in molecular biology and are also common in other life science streams like biochemistry, biophysics, genetics and involves the manipulation of genes or DNA and their analysis.

Okazaki fragments are formed during the DNA replication in a discontinuous way so many fragments of DNA are formed which are called Okazaki fragments then these fragments are joined by ligase enzymes.  

So Okazaki fragments are made autonomously during replication therefore no specific molecular technique is required to create Okazaki fragments.
