Question: Mitosis
Answer:
Division of the genetic material in the nucleus; followed immediately by cytokinesis
Question: Interphase
Answer:
period of the cell cycle between cell divisions in which the cell grows; includes G1 phase, S phase,
and G2 phase
Question: Gap 1 (G1) phase
Answer:
the first part of interphase where the cell grows
Question: S phase (synthesis)
Answer:
Phase is the cell cycle in which chromosomes are copied
,Question: Gap 2 (G2) phase
Answer:
the third part of interphase where the cell finishes growing and prepares for cell division
Question: Prophase
Answer:
first stage of mitosis, during which the cell's chromatin condenses into chromosomes, the nucleoli
disappear, chromosomes appear as sister chromatids, the mitotic spindle begins to form, and the
centrosomes move away from one another
Question: Metaphase
Answer:
Phase of mitosis during which chromosomes line up across the center of the cell (metaphase plate);
centrosomes are now at opposite poles
Question: Anaphase
Answer:
Shortest stage of mitosis, during which sister chromatids part, becoming independent chromosomes
Question: Cytokinesis
Answer:
Division of the cytoplasm
Question: Telophase
Answer:
Final stage of mitosis, during which two daughter nuclei form in the cell; nucleoli reappear and
chromosomes become less condensed
Question: Mitotic checkpoint
Answer:
Built-in control point where stop and go-ahead signals can regulate the mitotic cycle
, Question: Mitotic spindle
Answer:
Structure consisting of fibers made of microtubules and associated proteins; begins to form in the
cytoplasm during prophase
Question: Binary Fisson
Answer:
Meaning "division in half" refers to process of asexual reproduction of prokaryotes and single-celled
eukaryotes
Question: Anchorage dependence
Answer:
The requirement that a cell must be attached to a substratum (i.e. extra cellular matrix of tissue) in
order to initiate cell division.
Question: Density-dependent inhibition
Answer:
A phenomenon in which crowded cells stop dividing
Question: Meiosis
Answer:
Cell division that produces reproductive cells in sexually reproducing organisms
Question: Fertilization
Answer:
Union of gametes, culminating in fusion of their nuclei
Question: Zygote
Answer:
A fertilized egg, diploid, containing two haploid sets of chromosomes bearing genes from maternal
and paternal lines
