B2 Cell division

adult stem cells

stem cells that are found in adults that can differentiate and form a limited number of cells

cell cycle

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

Cloning

the production of identical offspring by asexual reproduction

Differentiate

the process where cells become specialised for a particular function

embryonic stem cells

stem cells from an early embryo that can differentiate to form the specialised cells of the body

Mitosis

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

stem cells

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

therapeutic cloning

a process where an embryo is produced that is genetically identical to the patient so the cells can then be used in medical treatments

Zygote

the single new cell formed by the fusion of gametes in sexual reproduction
