Question 2

Define cell cycle

Answer 2

The three-stage process of cell division in a body cell that involves mitosis and results in the formation of two identical daughter cells

Question 6

Define mitosis

Answer 6

Part of the cell cycle where one set of new chromosomes is pulled to each end of the cell forming two identical nuclei during cell division

Question 7

Define stem cells

Answer 7

Undifferentiated cells with the potential to form a wide variety of different cell types

Question 8

Define therapeutic cloning

Answer 8
