Molecular Cloning • Step 1: Ligation of DNA into vectors • Sticky ends • Different types of vectors • Step 2: Transformation • Putting recombinant DNA into host cell • Selecting the cells with inserted DNA • Distinguishing insert-containing vectors • Purifying the cloned DNA • Genomic and cDNA libraries
Step 2: Transformation Introduction of the vector+insert into a host • Common example = electroporation
Step 2: Transformation Selecting cells with a vector Selectable marker
Step 2: Transformation Selecting cells with a vector
Step 2: Transformation Distinguishing insert-containing vectors (if the process worked perfectly, this wouldn’t be necessary)
