Question

Quizplus · Accepted Answer

During interphase of the cell cycle, each chromosome consists of a single, unreplicated DNA molecule. This DNA molecule undergoes replication during the S phase of interphase, resulting in each chromosome consisting of two identical DNA molecules (called sister chromatids) that are held together at a structure called the centromere.
