Describe the mechanism of transformation.

Transformation is the process of what occurring with DNA?

Scientists must use what type of cells to transform DNA in the laboratory?

The DNA from a bacterium with the genotype a+ b+ c+ is used to transform a bacteria with the genotype a b c. Gene pairs were checked for cotransformation with the following results. Using these results determine which genes are linked.

In a transformation experiment, donor DNA was obtained from a prototroph bacterial strain (a⁺b⁺c⁺), and the recipient was a triple auxotroph (a⁻b⁻c⁻). What general conclusions can you draw about the linkage relationships among the three genes from the following transformant classes that were recovered?
