15 Questions
Match the following stages/events with their descriptions related to mitosis:
Cytokinesis = The stage that occurs immediately after mitosis, when the nuclei and organelles of the original cell split into two daughter cells Mitotic spindle checkpoint = An active signal that prevents a dividing cell from going into anaphase until all the chromosomes are lined up properly and attached to the spindle Endoreduplication = The duplication of genetic material in a cell without mitosis Non-disjunction = When a chromosome doesn’t fully separate, leaving one daughter cell with three copies of a specific chromosome, and the other daughter cell with just one copy
Match the following structures/terms with their descriptions related to mitosis:
Kinetochore = The protein structure that links chromosomes to microtubules during mitosis; each chromosome has two Phragmosome = The sheet of cytoplasm that divides a plant cell in two before mitosis Sister chromatids = Identical copies of a chromosome Chromatin = The mixture of DNA and protein molecules that makes up chromosomes
Match the following processes/events with their descriptions related to mitosis:
Mitosis = The process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell Endoreduplication = The duplication of genetic material in a cell without mitosis Cytokinesis = The stage that occurs immediately after mitosis, when the nuclei and organelles of the original cell split into two daughter cells Non-disjunction = When a chromosome doesn’t fully separate, leaving one daughter cell with three copies of a specific chromosome, and the other daughter cell with just one copy

What is the term for the stage that occurs immediately after mitosis, where the nuclei and organelles of the original cell split into two daughter cells?
Cytokinesis
What is the term for the identical copies of a chromosome?
Sister chromatids
What is the structure that links chromosomes to microtubules during mitosis?
Kinetochore
What occurs when a chromosome doesn’t fully separate, leaving one daughter cell with three copies of a specific chromosome and the other daughter cell with just one copy?
Non-disjunction
What is the process of duplicating genetic material in a cell without undergoing mitosis?
Endoreduplication
During mitosis, each chromosome has three kinetochores.
False
Phragmosome is a stage that occurs immediately after mitosis.
False
Endoreduplication is a process that involves mitosis.
False
The mitotic spindle checkpoint ensures all chromosomes are aligned properly before anaphase.
True
Non-disjunction results in both daughter cells having two copies of a specific chromosome.
False
Test your knowledge of the processes involved in mitosis and cell division. Learn about the stages of mitosis, the role of chromosomes, and the structures involved in cell division. Identify key terms and concepts related to this crucial biological process.
