Honors Biology Unit 4 | Questionswith correct Answers
the process that leads EUKARYOTIC cells of multicellular organisms to make more of
themselves; one cell becomes 2 identical daughter cells;
occurs in PHASES - ✔✔mitosis
includes G1, S, and G2 phases from the cell cycle; NOT considered a true part of mitosis -
✔✔interphase
DNA replicates (so chromosomes/chromatin replicates!) - ✔✔interphase
daughter centrioles (outside of nucleus) form next to parent centriole ( 2 become 4!) -
✔✔interphase
long, thin, single or double - ✔✔chromatin
short, fat, single - ✔✔chromosome
short, fat, double - ✔✔chromatid
centrioles w/dev daughter begin to move to opposite "poles" (opposite ends) - ✔✔prophase
nuc env and nucleolus start to disappear - ✔✔prophase
chromatin shortens and thickens (now called chromatid) - ✔✔prophase
, area where a pair of chromatids are attached - ✔✔centromere
disc that connects chromatids to the spindle - ✔✔kinetochore
cytoskeleton starts to break up; microtubules form asters and strands from centrioles to
kinetochores of chromatids - ✔✔prophase
starburst shape around centrioles - ✔✔asters
Made from the breakup of the cytoskeleton - ✔✔spindle
kinesis, a molecule (for movement) attaches to each pair of chromatids - ✔✔metaphase
chromatids move along spindle fibers until they are lined up in the MIDDLE (equator) of cell -
✔✔metaphase
chromatid pairs begin to separate; once separated each is known as a chromosome -
✔✔anaphase
chromosomes move to opposite ends of cells (poles...centrioles) - ✔✔anaphase
chromosomes uncoil and become chromatin - ✔✔telophase
cytoplasm starts to "pinch" in (animal cell) to separate the cell into 2 cells - ✔✔telophase
everything is undone that occurred in prophase! - ✔✔telophase
