Explanation:
G1 phase
Cell increases in size
Cellular contents duplicated
S phase
DNA replication
Each of the 46 chromosomes (23 pairs) is replicated by the cell
G2 phase
Cell prepares for cell division
M phase
Mitosis followed by Cytokinesis (cell separation)
Formation of two identical daughter cells
Phases of Mitosis
The M phase involves Mitosis which is the process of cell division. It is composed of:
Prophase
Nucleolus disintegrates
Nuclear membrane breakdown
Spindle fibres appear
Prometaphase
Spindle fibres attach to chromosomes
Chromosomes condense
Metaphase
Chromosomes align at the metaphase plate
Anaphase
Centromeres divide
Sister chromatids move to opposite poles
Telophase
Nuclear membrane reforms
Chromosomes decondense
Spindle fibres disappear
