,MITOSIS
• Mitosis is the process whereby one cell divides,
giving rise to two daughter cells that are
genetically identical to the parent cell.
• Each daughter cell receives the complete
complement of 46 chromosomes.
• Before a cell enters mitosis, each chromosome
replicates its deoxyribonucleic acid (DNA).
, Figure 2.3 Various
stages of mitosis.
In prophase,
chromosomes are
visible as slender
threads. Doubled
chromatids
become clearly
visible as
individual units
during metaphase.
At no time during
division do
members of a
chromosome pair
unite. Blue,
paternal
chromosomes; red,
maternal
chromosomes.
