Question

Choose whether the following examples Illustrate generalized transduction, specialized transduction, both, or neither. Drag and drop choices into the bins they describe GTAs and bacteriophages are both capable of changing the genetic material within a cell, causing new phenotypes to appear. The Ames test is used to determine whether exposure to different chemicals or other factors increases the mutation rate in cells. This is valuable in determining whether particular chemicals are mutagenic and potentially.

Explanation / Answer

Generalized Transduction

Any part of the host genome can be transferred

Gene transfer occurs through GTA

A relatively low percentage of cells exposed undergo transduction

Specialized Transduction

Only specific genes of DNA may be transduced

Transduction must involve a temperate phage

Transduced DNA is integrated into the host as part of a prophage

It is not necessary for phages to be defective for transduction

Both

Transduction may involve a virulent phage

It is accomplished by transducing particles

Neither

It involves a pilus
