Chromosomes
Structure
Structure
One half of a duplicated chromosome
What is, sister chromatid
The second phase of mitosis
What is, prophase
What occurrence within the cell does the cell cycle represent?
Prophase, Metaphase, Anaphase, Telophase
The division of the cytoplasm of the cell during cell division is referred to as?
Cytokinesis
In Prophase spindle fibers form between the poles?
What is, True.
Holds two sister chromatids together
What is, centromere
During this phase, chromosomes line up in the center of the cell and spindle fibers attach to the centromeres.
What is, Metaphase
What is the longest phase in the cell cycle?
what is, Interphase
In plant cells, a _______________ is built between the two daughter cells as they pull apart during cytokinesis.
Cell Plate
True or False: Cytokinesis is the division of the cell nucleus.
False. Cytokinesis is the division of the cytoplasm. Mitosis is the division of the nucleus.
Long, thin fibers of DNA and proteins
What is, chromatin
These hold identical chromatids together.
What is, centromeres
The cell cycle results in two genetically _________ cells.
What is, Identical
The pinching apart of the cytoplasm in an animal cell creates a ___________.
Cleavage furrow
Mitosis is when cells divide?
What is, True
Nucleic acid that makes up the bulk of a chromosome
What is, DNA
These form during Prophase when chromatin condenses.
What is, chromosomes
Cell cytoplasm divides
What is, cytokinesis?
What is the end result of cytokinesis?
Two identical daughter cells
Telophase is the 4th phase
What is, False It is like threads rather than rods.
Visible structure seen beginning in prophase
What is, chromosome
In this phase, a new nuclear envelope appears.
What is, telophase
The cell cycle produces what?
What is, Two daughter cells
In animal cells, this process involves the formation of a cleavage furrow, while in plant cells, it involves building a cell plate.
What is, cytokinesis
Telophase is the 4th phase
What is, False It is actually the 5th phase
