Cell Cycle

G1
• Cell increases its supply of proteins
• Increases many of its organelles such as mitochondria and ribosomes
• Grows in size• Typical cell 8-10 hours
![Page 4: Cell Cycle Just what does a cell do with all its time?](https://reader031.vdocument.in/reader031/viewer/2022020111/56649e545503460f94b4ba2d/html5/thumbnails/4.jpg)
S Phase
• DNA synthesis (replicates, makes a copy)
• Occurs between G1 and G2
• At the end the chromosomes consist of sister chromatids
• Typical cell 6-8hours

G2
• Time of protein synthesis essential for cell division
• Makes copies of centrioles
• Typical cell 2 hours

Interphase
Cell is performing its various metabolic activities
90% of cell cycle time

Mitosis
• Cell Divides
• Typical cell – 1 hour
