Phases of Mitosis
This is the first phase of mitosis where chromosomes become visible and spindle fibers begin to form
What is prophase?
These structures attach to chromosomes and help pull them apart during mitosis
What are spindle fibers?
Mitosis results in this number of daughter cells.
What is two?
Uncontrolled cell division can lead to this disease
What is cancer?
The cell cycle consists of mitosis and this other major phase.
What is interphase?
During this phase, chromosomes line up along the center of the cell
What is metaphase?
This organelle organizes the spindle fibers in animal cells
What is the centrosome/centrioles?
The daughter cells produced by mitosis are genetically ______ to the parent cell.
What is identical?
These proteins regulate the timing of the cell cycle.
What are cyclins?
During interphase, DNA replication occurs in this specific sub-phase.
What is the S phase?
In this phase, sister chromatids separate and move toward opposite poles
What is anaphase?
The region where sister chromatids are joined together
What is the centromere?
Mitosis occurs in these types of cells (somatic or gametes?).
What are somatic cells?
A failure in this process can result in cells with abnormal chromosome numbers.
What is nondisjunction?
This checkpoint ensures the cell is ready to enter mitosis.
What is the G2 checkpoint?
This phase involves the formation of two new nuclear envelopes around separated chromosomes
What is telophase?
These fibers extend from centrioles and attach to kinetochores
What are microtubules?
The purpose of mitosis in multicellular organisms
What is growth and repair?
This tumor suppressor gene is often mutated in cancer cells.
What is p53?
The phase where the cell grows and performs normal functions before DNA replication.
What is G1 phase?
Name the phase that occurs before mitosis where DNA is replicated
What is Interphase?
What is the term for the protein structure on chromatids where spindle fibers attach
What is the kinetochore?
Name one difference between mitosis and meiosis
What is mitosis produces two identical cells, while meiosis produces four genetically different cells?
Cells that exit the cycle and do not divide enter this phase.
What is G0 phase?
The phase where the cell completes division of the cytoplasm.
What is cytokinesis?
