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.
DNA replication occurs during the S stage of interphase.   Interphase is the stage between two mitotic or meiotic divisions. It can be slpit into three stages:G1, S a â¦ nd G2.   During G1 (gap 1), cells grow and build up ATP on preparation for DNA replication.   During the S (synthesis) phase the DNA is replicated.   During the G2 phase the cell prepares itself for the process of cell division (mitosis or meiosis).   See:   http://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookmito.html.
