Cutting and joining dna molecule

WebEnzymes Introduction Once pure samples of DNA has been obtained, the next step in gene cloning experiment is construction of rDNA molecule. To produce the rDNA molecule the vector and the gene to be inserted must be cut at specific points and joined together in a controlled manner. Cutting and joining are the two examples of DNA manipulative … WebMay 14, 2024 · The ends of the cut have an overhanging piece of single-stranded DNA. These are called "sticky ends" because they are able to form base pairs with any DNA …
