What does interphase consist of?

• G1-S-G2-meiosis-cytokinesis

• G1-S-G2

• Prophase-Metaphase-Anaphase-Telophase

• G1-S-G2-mitosis-cytokinesis

What happen in G1?

• prepare for cell division

• RNA is formed

• offspring cells grow to mature size

• cell's DNA is copied

What happens in 'S' phase?

• spindle fibers attach to chromosomes

• cell grows and prepares for cell division

• cell's DNA is copied

• resting spot between G1 and G2

What happens in G2?

• offspring cell grows to mature size

• cell continues to grow and prepare for division

• prepares for interphase

• spindle fibers pull chromosomes apart
