G10 Science: Bio Unit

Why would it be important to replicate DNA before a cell divides in mitosis or meiosis?

• In order for genetic information to be transferred into daughter cells.

• In order for the cell to be able to increase in size.

• In order for the DNA to be contained in the nucleus.

• In order for the cell to re-order the DNA sequencing in the new cells.

The end of mitosis results in  ____ to each other.

• 2 cells that are identical

• 4 cells that are identical

• 2 cells that are not identical

• 4 cells that are not identical

The end of meiosis results in  ____ to each other.

• 2 cells that are identical

• 4 cells that are identical

• 2 cells that are not identical
