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.
Replication occurs during interphase. Interphase is the stage of the cell cycle in which cells spend most (typically, more than 90%) of their time and perform their customary functions, including preparation for cell division. When this phase begins, the chromosomes have not yet replicated, but by the beginning of prophase replication is complete, so that each chromosome is composed of two sister chromatids.
