Skin cancer - the abnormal growth of skin cells - most often develops on skin exposed to the sun.
Cell that reproduce by asexual reproduction reproduce constantly.

Stage 1- Interphase Longest part of cell life Cell carries out normal
activities DNA in long strands called
chromatin Centrioles as a pair

• Chromatin doubles to form chromosomes (# doubles)
• Other cell parts also double• Editing of DNA to repair errors

• Chromosomes coil and become visible• Centrioles (or poles) appear and begin to
move to opposite end of the cell. Spindle fibers form between the poles.
• Nuclear membrane disappears.Centrioles

• Chromosomes line up in the middle of the cell on the spindle fibers.

• Chromatids (or halves of chromosomes) separate and begin to move to opposite ends of the cell.

• Chromatids finish separating. • Nuclear membrane reforms• Chromatids unwind and become
chromatin.
