He found that the number of sunspots rose and fell in a nearly regular cycle, lasting about 11 years. Interestingly, it soon turned out that big magnetic storms when the magnetic field was disturbed (typically by up to 1%) seemed to occur most frequently during the years with the most sunspots.
1 There are three stages of interphase: G1 (first gap), S (synthesis of new DNA), and G2 (second gap).  Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied.
In interphase, the cell is not undergoing cell division. The nucleus and chromatin are evident. Ed Reschke/Getty Images There are two stages or phases of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase.
