interphase Period of time where a cell carries out cell processes and replicates DNA prior to cell division
prophase Chromatin condenses into chromosomes
metaphase Chromosomes line up in the middle of the cell
anaphase Sister chromatids separate
telophase After the chromosome separates, the cell seals off, Final Phase of Mitosis.
chromatid Each half of the chromosome
chromosome A doubled rod of condensed chromatin; contains DNA that carries genetic information
centromere Area where the chromatids of a chromosome are attached
cell cycle An ordered sequence of events ; process of growth and division.
Centriole organelle the sends out spindle fibers
