WebThe interphase is the longest phase in the cell cycle and the stages of interphase include G1, S, G2 and in some special cases G0. All cells remain in interphase till it is time for division in the form of mitosis or meiosis. Most cells must mature to a certain stage before being able to divide, this period is none other than interphase. WebChromosome condensation in mitosis restarts chromatin to maintain normal transcription levels in interphase.

WebDuring interphase (G1 + S + G2), chromosomes are fully or partially decondensed, in the form of chromatin, which consists of DNA wound around histone proteins (nucleosomes).
