Unformatted text preview: Mitosis Vocabulary- Mitosis- o Cell cycle- is the orderly sequence of events that accomplish cell reproduction. o Interphase- is a time of synthetic activity of the cell; this is when protein synthesis and DNA replication occur. o Chromatin- during interphase, it is the replicated DNA material. o Mitosis- a process in which the chromosomes that were replicated in interphase are divided evenly between two daughter cells. o Chromosomes- at the initiation of mitosis the chromatin material condenses and becomes visible as linear structures. o Sister chromatids- these chromosomes consist of two separate bodies. o Centromere the sister chromatids are connected at a single point. o Prophase- at the beginning of mitosis, when the chromosomes become visible. o Prometaphase- the nuclear envelope fragments, bundles of microtubules ( spindle fibers ) extend from each pole toward the middle of the cell and the newly formed kinetochores (formed on each chromatids at the centromere). The sister chromatids begin to align along the center of the cell. o Metaphase- when the sister chromatids line up along the metaphase plate or plane (an imaginary plane in the center of the cell.) o Anaphase- as the protein of the spindle fibers contracts, the chromatids separate (becoming full-fledged chromosomes) and are moved passively to opposite poles....
