1. Which statement about site-directed in vitro mutagenesis is false? A. Point mutations can be created by making the change in 1 of the primers and having the primers (facing away from each other) extend around the whole plasmid.

B. Deletions can be created by having the 5' ends of the primers separated by the region you want deleted, therefore it won't be amplified during PCR.

C. Insertions can't be made because you can't add extra DNA to the primers used to amplify the plasmid.
