CELL CYCLE - Coggle Diagram
CELL CYCLE
-
G1 phase (Gap 1): Cell growth and normal metabolic activities occur. The cell prepares for DNA replication.
S phase (Synthesis): DNA replication occurs. Each chromosome is duplicated to form sister chromatids.
G2 phase (Gap 2): Further cell growth and preparation for cell division occur. The cell checks for DNA errors and prepares for mitosis.
Mitotic (M) Phase:
Mitosis: Nuclear division occurs, resulting in the formation of two genetically identical daughter nuclei.
-
-
-
-
Spindle fibers shorten, pulling chromatids apart.
-
Cytokinesis: Division of the cytoplasm occurs, resulting in two distinct daughter cells.
-
-
-
Chromosomes are condensed structures of DNA that are visible under a microscope during cell division.
-
In humans, there are 46 chromosomes in each cell
-
Sister chromatids are two identical copies of a single chromosome that are produced by DNA replication during the S phase of the cell cycle.
-
-
Checks whether the cell has growth factors, and cell size before entering the S phase
-
-
-
If the damage cannot be repaired, the cell may undergo apoptosis (death of cells)
