WebIn the first step, called interphase, the DNA strand of a chromosome is copied (the DNA strand is replicated) and this copied strand is attached to the original strand at a spot called the centromere. This new structure is called a bivalent chromosome. WebOnce the chromosomes are replicated, the cell moves into the G2 phase of interphase and awaits mitosis. The S phase is called synthesis because making a copy of the chromosome requires new DNA production, or synthesis.
