Question

Generalized and Specialized Transduction 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 whether particular chemicals are mutagenic and potentially carcinogenic

Explanation / Answer

Answer

Generalized Transduction:

Any part of the host genome can be transferred.

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.

Transudced Dna is integrated into the host as a part of prophage.

Both:

Transduction may involve a virulent phage.

It is accomplished by transducing particles.

Neither:

It involves a pilus.

It is not necessary for phages to be defective for transduction.

Gene transfer occurs through GTA.
