Proteins P1 and P2 bind to each other to form a complex. This complex has a high binding affinity to a specific element on the promoter sequence of a gene X , thus transcribing it. The product of gene X is responsible for the accumulation of red pigment in some plants. Under drought stress, another protein P3 binds to P2 and prevents its binding to P1 and the plants appear pale. The following table depicts a represen

Options

  1. AMutant-3 has mutation in gene coding for protein P1 or protein P2.
  2. BMutant-2 has mutation in genes coding for either protein P1 or protein P3.
  3. CMutant-2 has mutation in gene coding for protein P3.
  4. DMutant-1 has mutation in gene coding for protein P3.

Correct answer

C. Mutant-2 has mutation in gene coding for protein P3.
