1. ___________________________The reproduction of cells.
2. ___________________________In a duplicated chromosome, the region on each sister
chromatid where it is most closely attached to the other chromatid by proteins that bind to the
centromeric DNS. Other proteins condense the chromatin in that region, so it appears as a
narrow ‘’waist” on the duplicated chromosome.
3. ___________________________A structure present in the cytoplasm of animal cells that
functions as a microtubule-organizing center and is important during cell division. A centrosome
has two centrioles.
4. ___________________________An ordered sequence of events in the life of a cell, from its
origin in the division of a parent cell until its own division into two. The eukaryotic cell cycle is
composed of interphase, and M phase.
5. ___________________________A Cellular structure consisting of one DNA molecule and
associated protein molecules.
6. ___________________________The process of cytokinesis in animal cells, characterized by
pinching of the plasma membrane. The succession of rapid cell divisions without significant
growth during early embryonic development that converts the zygote to a ball of cells.
7. ___________________________The first sign of cleavage in an animal cell; a shallow groove
around the cell in the cell surface near the old metaphase plate.
8. ___________________________A membrane-bounded flattened sac located in the middle of a
dividing plant cell inside which the new cell wall forms during cytokinesis
9. ___________________________A cellular protein that occurs in a cyclically fluctuating
concentration and that plays an important role in regulating the cell cycle.
10. ___________________________A haploid reproductive cell, such as an egg or a sperm.
Gametes unite during sexual reproduction to produce a diploid zygote.
11. ___________________________The genetic material of an organism or virus; the complete
complement of an organism’s or virus’s genes along with its noncoding nucleic acid sequence.
12. ___________________________A protein that must be present in the extracellular
environment for the growth and normal development of certain types of cells.
13. ___________________________A process of nuclear division in Eukaryotic cells conventionally
divided into 5 stages. Conserves chromosome number by allocating replicated chromosomes
equally to each of the daughter nuclei.
14. ___________________________The phase of the cell cycle that include mitosis and cytokinesis.
15. An assemblage of microtubules and associated proteins that is involved in the movement of
chromosomes during mitosis.
16. ___________________________A nondividing state occupied by cells that have left the cell
cycle, sometimes reversibly.
17. ___________________________The first gap, or growth phase, of the cell cycle consisting of
the portion of interphase before DNA Synthesis begins.
18. ___________________________The second gap, or growth phase, of the cell cycle, consisting of
the portion of interphase after DNA synthesis occurs.
19. ___________________________A radial array of short microtubules that extends from each
centrosome toward the plasma membrane in an animal cell undergoing mitosis.

20. ___________________________A cyclically operating set of molecules in the eukaryotic cell
that both triggers and coordinates key events in the cell cycle.
21. ___________________________The fourth stage of mitosis, in which the chromatids of each
chromosome have separated and the daughter chromosomes are moving to the poles of the
cell.
22. ___________________________The third stage of mitosis, in which the spindle is complete and
the chromosomes attached to microtubules at their kinetochores, are all aligned at the
metaphase plate.
23. ___________________________An imaginary structure located at the plane midway between
the two poles of a cell in metaphase in which the centromeres of all the duplicated
chromosomes are located.
24. ___________________________The first stage of mitosis, in which the chromatin condenses
into discrete chromosomes visible with a light microscope, the mitotic spindle begins to form,
and the nucleolus disappears but the nucleus remains intact.
25. ___________________________The second stage of mitosis, in which the nuclear envelope
fragments and the spindle microtubules attach to the kinetochores of the chromosomes.
26. ___________________________The synthesis phase of the cell cycle; the portion of interphase
during which DNA is replicated.
27. ___________________________Two copies of a duplicated chromosome attached to each
other by proteins at the centromere and, sometimes, along the arms. While joined, two sister
chromatids make up one chromosome. Chromatids are eventually separated during mitosis or
meiosis II.
28. ___________________________Any cell in a multicellular organism except a sperm or egg or
their precursors.
29. ___________________________Site where the replication of a DNA molecule begins, consisting
of a specific sequence of nucleotides.
30. ___________________________The fifth and final stage of mitosis, in which daughter nuclei are
forming and cytokinesis has typically begun.
31. ___________________________The spread of cancer cells to locations distant from their
original site.
32. ___________________________A mass of abnormal cells with specific genetic and cellular
changes such that the cells are not capable of surviving at a new site and generally remain at the
site of the tumor’s origins.
33. ___________________________A cancerous tumor containing cells that have significant
genetic and cellular changes and are capable of invading and surviving in new sites. Can impair
functions of one or more organs.
34. ___________________________A method of asexual reproduction by “division in half”. In
prokaryotes, binary fission does not involve mitosis, but in single celled eukaryotes that undergo
binary fission, mitosis is part of the process.
35. ___________________________The phenomenon observed in normal animal cells that causes
them to stop dividing when they come into contact with one another.

36. ___________________________The requirement that a cell must be attached to a substratum
in order to initiate cell division.
37. ___________________________The conversion of a normal cell into a cell that is able to divide
indefinitely in culture, thus behaving like a cancer cell.
38. ___________________________A structure of proteins attached to the centromere that links
each sister chromatid to the mitotic spindle.
39. ___________________________The division of the cytoplasm to form two separate daughter
cells immediately after mitosis, meiosis I, or meiosis II.
40. ___________________________The period in the cell cycle when the cell is not dividing. During
interphase, cellular metabolic activity is high, chromosomes and organelles are duplicated, and
cell size may increase. Often accounts for up to 90% of the cell cycle.
