Cell reproduction

What are the stages of Interphase?

G1 Phase (First Gap)
S Phase (Synthesis)
G2 Phase (Second Gap)

G1 Phase (First Gap)

Cell growth, metabolism, and preparation for DNA replication.

S Phase (Synthesis)

DNA replication, producing two identical copies of each chromosome.

G2 Phase (Second Gap)

Further cell growth and preparation for mitosis, including protein synthesis and organelle production.

What happens during Prophase in Mitosis?

Chromatin Condensation: Chromatin condenses into visible chromosomes.
Nuclear Envelope Breakdown: The nuclear envelope disassembles.
Mitotic Spindle Formation: Spindle fibers form and attach to chromosomes.

What occurs during Metaphase in Mitosis?

Chromosome Alignment: Chromosomes align along the metaphase plate.
Spindle Fiber Attachment: Spindle fibers attach to centromeres of chromosomes.

What happens during Anaphase in Mitosis?

Chromatid Separation: Sister chromatids are pulled apart to opposite poles of the cell.
Cytokinesis Begins: Cell membrane starts pinching inwards.

What are the key events of Telophase in Mitosis?

Chromosome Decondensation: Chromosomes de-condense into chromatin.
Nuclear Envelope Reformation: New nuclear envelopes form around each set of chromosomes.
Spindle Fiber Disassembly: Spindle fibers break down.

What is Cytokinesis and what is its role?

Definition: Division of the cytoplasm and organelles.
Function: The cell membrane pinches inwards, producing two genetically identical daughter cells.
