What occurs during prophase?
Interphase is the phase of the cell cycle in which a typical cell spends most of its life. During this phase the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell in which the cell obtains nutrients and metabolizes them grows reads its DNA and conducts other "no…

Meiosis involves two rounds of chromosome segregation and thus undergoes prophase twice resulting in prophase I and prophase II. Prophase I is the most complex phase in all of meiosis because homologous chromosomes must pair and exchange genetic information. Prophase II is very similar to mitotic prophase. Prophase I is divided into five phases: leptotene zygotene pachytene diplotene and diakinesis. In addition to the events that occur in mitoticprophase several crucial events occur within these phases su…
Meiosis is divided into meiosis I and meiosis II which are further divided into Karyokinesis I and Cytokinesis I and Karyokinesis II and Cytokinesis II respectively. The preparatory steps that lead up to meiosis are identical in pattern and name to interphase of the mitotic cell cycle. Interphase is divided into three phases: • Growth 1 (G1) phase: In this very active phase the cell synthesizes its vast array of proteins includin…
During prophase which occurs after G 2 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.
Genetic crossing-over a type of recombination occurs during the pachytene stage of prophase I. In addition another type of recombination referred to as synthesis-dependent strand annealing (SDSA) frequently occurs. SDSA recombination involves information exchange between paired homologous chromatids but not physical exchange.
