◉ Interphase.
Answer: Cell grows, performs its normal functions, and prepares for
division; consists of G1, S, and G2 phases


◉ G1 phase.
Answer: The first gap, or growth phase, of the cell cycle, consisting of
the portion of interphase before DNA synthesis begins; longest
phase


◉ S Phase (interphase of mitosis).
Answer: Synthesis and replication of chromosomes


◉ G2 phase.
Answer: stage of interphase in which cell duplicates its cytosol and
organelles


◉ mitosis (M) phase.
Answer: when the cells nucleus divides

, ◉ Cytokinesis (C) phase.
Answer: division of the cytoplasm forming two new daughter cells
which are identical copies of the original parent cell


◉ homologous chromosomes ("homologs" in a diploid cell).
Answer: Chromosomes that have the same sequence of genes and
the same structure


◉ homologs.
Answer: Members of a pair of chromosomes


◉ Non-replicated chromosome.
Answer: a chromosome that has NOT gone through the process of
replication and only contains 1 double helix molecule of DNA


◉ replicated chromosome.
Answer: A chromosome that has been copied; consists of two
identical chromatids, each containing one double-helical DNA
molecule


◉ sister chromatids.
Answer: Identical copies of a chromosome; full sets of these are
created during the S phase of interphase.
