Restriction endonucleases

Vedclass · Answer

(A) In genetic engineering,the ability to cut $DNA$ at specific sites and join them to vectors is fundamental. Restriction endonucleases are enzymes that act as 'molecular scissors' to cut $DNA$ at specific recognition sequences. $DNA$ ligase is the enzyme responsible for joining $DNA$ fragments together. However,the foundational breakthrough that allowed for the precise manipulation and insertion of foreign $DNA$ into a host genome was the discovery of restriction endonucleases,which enable the creation of recombinant $DNA$ molecules. Therefore,the correct answer is $A$.

The insertion of $DNA$ in genetic engineering is attributed to the discovery of which of the following?
