The preprophase band disappears during nuclear envelope breakdown and spindle formation in prometaphase. During prophase, which occurs after G interphase, the cell prepares to divide by tightly condensing its chromosomes and initiating mitotic spindle formation. During interphase, the genetic material in the nucleus consists of loosely packed chromatin. At the onset of prophase, chromatin fibers condense into discrete chromosomes that are typically visible at high magnification through a light microscope. In this stage, chromosomes are long, thin and thread-like. Each chromosome has two chromatids. The two chromatids are joined at the centromere.', 'During prophase, which occurs after G interphase, the cell prepares']}}]}, {'provenance': [{'wikipedia_id': '2991457', 'title': 'Synapsis', 'section': 'Section::::Abstract.', 'start_paragraph_id': 1, 'end_paragraph_id': 1, 'meta': {'evidence_span': ['Synapsis (also called syndesis) is the pairing of two homologous chromosomes that occurs during meiosis.
