Task:
Identify Interphase as well as each phase
of mitosis. Use the descriptions below to
assist you.
Terms to Use:
Anaphase - the phase of mitosis in which the
Interphase - the phase of a cell's life cycle in which DNA is
chromosomes begin to separate.
Centrioles - paired cylindrical organelles, arranged at
right angles to each other, located at the center of a
microtubule.
Centromeres - a centromere is the constricted region of a
nuclear chromosome - microfibers attach to the
centromere during mitosis.
Chromosomes - structures in the nucleus that contain
DNA molecules that contain the genes.
replicated.
Microtubules - tiny filaments (about 25 nanometers in diameter) that are
active in mitosis.
Metaphase - the phase of mitosis in which the chromosomes line up
at the equator (the central plane) of the cell.
Prophase - the phase of mitosis in which the duplicated
chromosomes condense, the nuclear envelope dissolves, and centrioles
divide and move to opposite ends of the cell.
Telophase - the last phase of mitosis, when the chromosomes migrate
to opposite ends of the cell, two new nuclear envelopes form, and the
chromosomes uncoil.
