Examine the diagram and identify the correction option.

Options

  1. AC-Transformation does not occur, no change and only R-strain will be observed.
  2. BA-Transformation occurs and new R-strain will be converted to S-strain
  3. CB-Transformation occurs and all the S-strain will be transformed to R-strain
  4. DB-Transformation does not occur and new S-strain appears mixed with R-strain

Correct answer

A. C-Transformation does not occur, no change and only R-strain will be observed.

Step-by-step solution

The liquid extract from dead virulent S-strain bacteria with normal R-strain bacteria is present in the culture vessels A, B and C. Different enzymes were added to the culture vessels and a brief incubation was given for the growth of the organism. The culture vessel A and B will undergo a transformation and new S-cells appears mixed with R-cells and in C vessel transformation does not occur, no change and only R cells will be observed. This is because the transformation principle tells that DNA is the genetic mate
