Simple Cloning topics include: Vectors, transformation and hosts, cloning using a simple plasmid and alpha complementation, madifications in linkers, adaptors and cloning methods. DNA cloning is a technique that creates multiple copies of a DNA segment. It can be used to isolate and characterize genes or to produce proteins like insulin.  Here are some basic steps for cloning: Isolate or amplify foreign DNA using PCR Purify the DNA Cut the DNA with restriction enzymes Mix the DNA with a vector that has been cut with the same restriction enzymes Stitch the DNA back together with DNA...
