BIO 121 Exam 3 Review Questions and
Complete Solutions
Binary fission ✅a method of asexual reproduction; "division in half"; involves mitosis in
eukaryotes

Mitosis ✅a process of nuclear division in eukaryotes

What are the 5 stages of Mitosis? ✅1. Prophase
2. Prometaphase
3. metaphase
4. anaphase
5. telophase

Meiosis ✅A modified type of cell division in sexually reproducing organisms consisting
of 2 rounds of cell division, but one round of DNA replication. Half number of
chromosome sets as original cell

Sexual Reproduction ✅A type of reproduction in which two parents give rise to one
offspring that have unique combination of genes inherited by both parents via gametes

Asexual Reproduction ✅A type of reproduction with one parent; no fusion of gametes;
budding, division of a single cell; genetically identical to the parent

Haploid ✅A cell containing one set of chromosomes

Diploid ✅A cell containing two sets of chromosomes; one from each parent

Prophase ✅1st stage of mitosis; chromatin (chromosomes) condense

Prometaphase ✅2nd stage of mitosis; nuclear envelope fragments; each chromatid
gets a kinetochore

Metaphase ✅3rd stage of mitosis; Chromosomes line up in the middle of the cell

Anaphase ✅4th stage of mitosis; sister chromatids separate from each other and are
pulled towards opposite ends of the cell; shortest stage

Telophase ✅5th stage of mitosis;2 nuclei form; mitotic spindle breaks down

Cytokinesis ✅The division of the cytoplasm to form two separate daughter cells

, Interphase ✅The period in the cell cycle when the cell is not dividing ; cellular
metabolic activity is high; 90 % of cell cycle

Chromosome ✅A cellular structure carrying genetic material; in nucleus; made up of a
very long DNA molecule and proteins

Tubulin ✅Globular protein that constructs the wall of the microtubules

Sister Chromatid ✅2 copies of a duplicated chromosome attached to each other at the
centromere (sometimes along arms)

Microtuble ✅A hallow rod composed of tubulin proteins that make up part of the
cytoskeleton in all eukaryotic cells

Centrosome ✅in cytoplasm of animal cells; functions as a microtubule organizing
center

Centromere ✅the region on each sister chromatid where they are most closely
attached to each other ; in a duplicated chromosome

Mitotic spindle ✅An assemblage of microtubules ; involved in movement of
chromosomes

Kinetochere ✅A structure of proteins attached to the centromere that links each sister
chromatid to the mitotic spindle

Homologous Chromosomes ✅A pair of chromosomes of the same length, centromere
position and staining pattern that possesses genes for the same characters at
corresponding loci

Separase ✅An enzyme that starts the anaphase stage of mitosis; separates the sister
chromatids

Cyclin ✅A cellular protein that occurs in a cyclically fluctuating concentration and that
plays an important role in regulating the cell cycle

Cyclin dependent kinase (cdk) ✅A protein kinase that is active only when attached to a
particular cyclin

MPF ✅Maturation -promoting factor; protein complex required for a cell to progress
from late interphase to mitosis;helps initiate mitosis
