Wild type E. coli metabolizes the sugar lactose by expressing the enzyme ß-galactosidase. You have isolated a mutant that you call lac1-, which cannot synthesize ß-galactosidase and cannot grow on lactose (Lac-). During an condition  isolate  a second Lac– mutation, which you designate lac2-. Using P1 phage on this strain and use the resulting phage lysate to infect the lac2- strain, selecting for   Kanr   transductants. In this case, all 100   Kanr   transductants that are examined are Lac–. What does this result tell you about the relationship between the lac1- and lac2- mutations?

With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

 

 

Match the babies up with their actual parents.
