Interphase
True or False: The typical cell spends most of its life in interphase.
True
What is a chromosome?
The shortest phase of mitosis is
metaphase
The type of proteins/ structures that allow the processes of anaphase to work.
microtubules (spindle fibers)
True or False: In the telophase, the cell is nearly done dividing.
True
The division of the cytoplasm to form two new cells.
What is cytokinesis?
DNA condenses making it easier to pull them apart.
What is a chromosome?
The first part of the interphase; consists of major cell growth.
What is the G1/ Gap 1 phase?
Starts to form.
What are the spindle fibres?
All the chromosomes align at this place.
What is the cell equator?
What happens when centrosomes is broken.
What is the sister chromatids separate.
It is broken down into its building blocks during this phase.
What is the mitotic spindle?
The phase just before cytokinesis.
What is telophase?
The regions of DNA where the sister chromatids are most tightly connected. Used for the attachment of spindle fibers during division.
What are centromeres?
The phase when the cell synthesizes a complete copy of the DNA in its nucleus
What is the S phase?
Organelle responsible for making ribosomes disappears.
What is a Nucleolus?
The mitotic spindle.
What captures the chromosomes and lines them up in the middle of the cell?
The portion of the chromosome that the spindle fibers attach to.
What is the centromere?
The number of new nuclei that forms during telophase.
What is 2 nuclei; one for each set of chromosomes?
The structure that forms down the middle of the cell at the end of a plant’s cytokinesis phase and its function.
What is the Cell plate; splits the cell into two daughter cells?
The protein structure that equally divides the chromosomes in a parental cell into two daughter cells; makes sure the chromosomes are organized, aligned, and assorted during mitosis.
What are spindle fibers?
The cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.
What is the G2 phase?
This breaks down, releasing the chromosomes.
What is the Nuclear Envelope?
The cell doesn't enter anaphase and mitosis stops until the cell is fixed.
What occurs when a chromosome is not properly aligned or attached?
Two chromatids split apart.
What are Chromosomes?
The two organelles that begin to reappear during this phase.
What are nuclear membranes and nucleoli?
The structure that forms down the middle of the cell at the end of an animal's cytokinesis phase and its function.
What is the cleavage furrow?
Organelle that contains all eukaryotic DNA; split during mitosis
What is the nucleus?
The resting phase for cells that have exited the cell cycle
What is G0?
The primary end product of prophase.
What are visible chromosomes?
The end product of metaphase.
What is all of the chromosomes are lined up in the center of the cell?
Sister chromatids separate from each other and are pulled towards opposite ends of the cell.
What is the end product of anaphase?
The spindle disintegrates, and the chromosomes recoil, forming chromatin.
What is the end product of telophase?
What are two cells that have identical copies of DNA?
identical daughter cells
This organelle is responsible for making spindle fibers for cell division.
What are centrioles?
