One of the chromosomes in a nucleus has a telomere which contains many repeats of the base sequence ttaggg.
This chromosome was extracted from four different cells and the total number of bases in the telomere was determined.
The total number of bases that was found in the cell that had undergone the most mitotic divisions will be given by the formula
2.n
If we consider single repeat for each base, the total number of bases after each mitotic divison will be
2*6= 12
So, the base which has the maximum number of repeats have undergone the most mitotic divisions.

Answer: 5548
Explanation: telomeres getting shorter each time mitosis takes place. So, the most mitosis means the shortest bases number.
