The rule is, once a rollover is completed and a 72(t) is setup to pay out an income stream, it must continue until the age of 59 Â½ has been reached or for a minimum of 5 years, whichever comes last. For example, if you start a 72(t) at the age of 57, it must run until you are age 62, then it stops.
Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division. If all conditions are ideal, the cell is now ready to move into the first phase of mitosis.
The stage of the cell cycle when a cell is preparing itself to duplicate is called interphase. Most of the cell's life is spent in this stage. While preparing to reproduce, the cell makes more cytoplasm (the gel-like substance found inside the cell membrane that bathes the organelles) and increases its supply of proteins.
