Question

Two important steps involved in genetic engineering are cutting the desired gene from its genome, then cutting the vector genome and pasting the gene into it.
How is this carried out?



Using the same restriction enzyme for cutting the desired gene and the vector and using ligase for pasting the gene into the vector



Using two different restriction enzymes for cutting the desired gene and the vector and polymerase for pasting the gene into the vector



Using the same ligase for cutting the desired gene and the vector and a restriction enzyme for pasting the gene into the vec
