Use the diagram and information to answer the following questions.
Cell cycle diagram ap bio. Interphase represents the. Period of the cell cycle between cell divisions g1 s and g2 phase mitosis a type of eukaryotic cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus typical of ordinary tissue growth. The cell cycle is composed of interphase g1 s and g2 phases followed by the mitotic phase mitosis and cytokinesis and g0 phase.
Meiosis and genetic diversity. Chromosomal crossover in meiosis i. The cell cycle of yeast cells grown in the nutrient poor environment is approximately what percent of yeast cells grown in the nutrientrich environment.

Phases of the cell cycle. This is the currently selected item. Phases of mitosis.
In eukaryotes the cell cycle consists of a long preparatory period interphase followed by mitosis and cytokinesis. The first stage in the first meiotic division of meiosis characterized by having five sub stages namely leptotene zygotene pachytene diplotene and diakinesis and essential mainly for the exchange of dna between homologous chromosomes via a process called homologous recombination and the crossover at chiasmata between non sister chromatids. The g1 phase lasts 6 hours the s phase lasts 8 hours the g2 phase lasts 6 hours and the m phase lasts 8 hours.
