Answer :

With the exception of eating foreign DNA, all of the following justifications for bacterial uptake of foreign DNA are advantageous.

The transformation of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacterium is known as DNA absorption. This DNA uptake in gram-negative bacteria can be accomplished by breaking through the outer membrane. In contrast, DNA uptake in gram-positive bacteria occurs with passage over the cytoplasmic membrane and is comparable to that of gram-negative bacteria.

Bacterial DNA absorption is advantageous since it aids in the creation of recombinants that may be applied to a variety of situations. Patients with hereditary diseases can employ DNA uptake to repair broken chromosomes and DNA.

In organisms like bacteria, new genes can be introduced for various purposes.

Option A is the right response, so that is what it is.

The complete question is:-

All of the following are reasons it might be beneficial for bacteria to take up foreign DNA EXCEPT that Question 77 options: a) DNA could be used for food by bacteria. b) the uptake of foreign DNA would result in potentially beneficial recombinants. c) the uptake of foreign DNA might allow a cell to repair damaged chromosomes. d) the uptake of foreign DNA could allow completely new genes with new functions to enter the recipient cell. e) the uptake of foreign DNA could result in the breakage of the plasma membrane of the recipient cell.
