The following ratio is generally constant for a given species:

Options

  1. AA + G / C + T
  2. BT + C / G + A
  3. CG + C / A + T
  4. DA + C / T + G .

Correct answer

C. G + C / A + T

Step-by-step solution

The C + G / A + T ratio varies from organism to organism among the prokaryotes), but within (particularly the limits of experimental error, A = T and C = G . Related Theory Erwin Chargaff discovered that the number of nitrogenous bases in the DNA was present in equal quantities. The amount of A is equal to T , whereas the amount of C is equal to G , i.e., A=T ; C=G
