Q. Consider the following statements. (A) The number of base pairs in a DNA molecule remains the same in all organisms of different species. (B) The length of DNA is defined as number of nucleotides or base pairs. Select the correct option
A) A is true, B is false
B) Both A and B are true
C) A is false, B is true
D) Both A and B are false
