series of mutations‚ or changes in DNA‚ that make them divide more quickly‚ escape internal and external controls on division‚ and avoid programmed cell death. The cell cycle is divided into three parts‚ Interphase‚M phase‚ and Cytokinesis. The first part of the cell cycle starts out with interphase‚ the

Cycle and Mitosis THE CELL CYCLE The cell cycle‚ or cell-division cycle‚ is the series of events that take place in a eukaryotic cell between its formation and the moment it replicates itself. These events can be divided in two main parts: interphase (in between divisions phase grouping G1 phase‚ S phase‚ G2 phase)‚ during which the cell is forming and carries on with its normal metabolic functions; the mitotic phase (M mitosis)‚ during which the cell is replicating itself. Thus‚ cell-division

that studied the each phase in the cell cycle.The hypothesis for this lab stated‚ "Interphase will be the longest phase and anaphase will be the shortest phase.” Mitosis is the process where of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. The cell cycle is the cycle of growth and asexual reproduction of a cell‚ consisting of interphase followed in actively dividing cells by prophase‚ metaphase‚ anaphase‚ and telophase

Mitosis has five phases: interphase‚ prophase‚ metaphase‚ anaphase and telophase. Interphase The DNA duplicates during interphase to prepare for mitosis. Chromosomes are not clearly discerned in the nucleus. Prophase Chromatin in the nucleus begins to condense and becomes visible in the light microscope as chromosomes. The nuclear

to be able to compare the process of mitosis between plant and animal cells. Background: • Mitosis: This is the process by which a cell duplicates the chromosomes in its cell nucleus in order to generate two identical daughter nuclei. • Interphase: This particular stage is divided into three phases‚ G1 (first gap)‚ S (synthesis)‚ and G2 (second gap). During all three phases‚ the cell grows by producing proteins and other organelles within the cytoplasm. However‚ chromosomes are replicated

phases interphase and mitotic phase. The time spent in these phases depends upon the type of cell and its particular developmental or physiological state. Cells comprising rapidly growing tissues‚ like those in the root tip of a plant spend a comparatively long time in the mitotic phase‚ whereas those cells comprising slow-growing tissues would spend most of their lives in interphase. Non-dividing cells remain in interphase and never enter the mitotic phase. (Lab Manual 64) Interphase is the
