Question

A bird cell with 10 chromosomes goes through the cell cycle. How many daughter cells are created at the end of 3 cell cycles AND how many chromosomes are in each daughter cell if none of them die?

Answer 1

At the end of one cell cycle, a cell with 10 chromosomes will divide into two daughter cells, each with 10 chromosomes.

After 2 cell cycles:

One cell divides into two, so there are now 2 cells.

Each of those two cells divide into two, so there are now 4 cells.

Each of those four cells divide into two, so there are now 8 cells.

After 3 cell cycles:

One cell divides into two, so there are now 16 cells.

Each of those 16 cells divide into two, so there are now 32 cells.

Each of those 32 cells divide into two, so there are now 64 cells.

So at the end of 3 cell cycles, there are 64 daughter cells.

Each daughter cell will have 10 chromosomes, since the number of chromosomes did not change during the cell cycles.
