Chapter 6

Insertion or deletion of nucleotides causes a 'frameshift' in how mRNA is transcribed. Occurs during DNA synthesis. Ethinium Bromide Used in DNA staining for electrophoresis; an intercalating agent which causes frameshift mutations in living cells. Indirect Selection Allows for the isolation of auxotrophs from wild-type parents (auxotrophs need an additional nutrient). Requires making a plate copy with velvet and looking for the colonies which do not grow on the nutrient-limited plate....
