Nuclear envelope fragments and disappears.Įarly prophase late prophase centrioles spindle fibers aster fibers nuclear envelope disappearing centromere Prophase.Spindle fibers form and attach from centrioles to centromeres by kinetochores.Centrioles move apart (not found in plants). Chromatin material condenses into chromosomes, consisting of twosister chromatids.Prophase- prometaphase- metaphase-anaphase-telophase A chromatid is a chromatid as long as it is held in association with a sisterchromatid at the centromere.A replicated chromosome consist of two strands of identical chromosomal material called chromatids (sister chromatids).Ĭentromere chromatid chromosome chromatid Answer:.DNA double helix Histone proteinsĬhromosome S phase: chromosomes replicate chromatid chromosome chromatid centromere Answer: Chromatin is a long, thin fiber that is folded and coiled to form chromosomes.A chromosome is made up of a DNA - histone protein complex called chromatin. chromatin Nuclear membrane cell membrane nucleolus G2 (gap) phase: a.Ĝellular growth and preparation for M phase. protein synthesis and metabolic activities.
