how about the cell membranee...where diagram was drawn and 3 statements were there about C02 02 and movement of H2O? which ones were correct?

 

[A*****]

how did you find out the number of bases with cell that had maximum mitotic divisions...(the answers were in 5000s,...four cells....telomeres?)

A chromose contained a telomer consisting of MANY repeated sequences of those 6 bases not just those 6....after every division the number decreased by one so it was 6x-1 = the number given in the option....only C was fitting and the rest all didn't gave answer as a whole number
