Centromeric DNA was initially defined in ___________

Centromeric DNA was initially defined in ___________ Correct Answer Yeast

Centromeric DNA sequences were initially identified in yeasts, where their functions were assayed by following the segregation of plasmids at mitosis. Plasmids that contain functional centromeres segregate like chromosomes and are equally distributed to daughter cells following mitosis.

A tank has an optional adjustable outlet pipe that can be attached to the tank at any height we want. This outlet pipe drains water from the tank at a constant rate, while the tank is being filled using another inlet pipe at a constant rate. If the outlet, pipe is attached at half the height of the tank, the tank, which is initially empty gets filled in 18 hours. If the outlet pipe is attached at height equal to two third height of the tank, the tank, which is initially empty, is filled in 16 hours. In how many hours will the tank, which is initially empty, be completely filled if the outlet pipe is not attached to the tank?

Each of four boys P, Q, R and S, had a few chocolates with him. P first gave 33.33% of the chocolates with him to Q, Q gave 25% of what he then had to R and R gave 20% of what he then had to S. Finally, all the four boys had an equal number of chocolates. If P initially had 160 chocolates more than the number of chocolates that Q had initially. Then, find the difference between the numbers of chocolates that R and S initially had?
