Mitosis 1
What is the purpose or benefits of mitosis in multicellular organisms?
What is to grow, repair, replace, reproduce, and regenerate.
The phase when chromosomes condense and the nuclear membrane begins to break down.
What is prophase?
What structure pulls chromatids apart during mitosis?
Spindle fibers
The results of Mitosis
What are two genetically identical cells?
Which phase of mitosis is the longest?
Prophase
A eukaryotic animal cell entering mitosis contains two sets of chromosomes (2n). This term describes that chromosome number.
What is diploid?
During which phase do chromosomes line up in the middle of the cell?
What is metaphase?
What are the identical copies of a chromosome called, which are connected at a centromere?
Sister chromatids
How many divisions occur in mitosis?
One division
What phase does the cell spend most of its life in, before entering mitosis?
Interphase
The structure that forms in plant cells during cytokinesis.
The cell plate?
In what phase do sister chromatids separate and move to opposite poles?
What is Anaphase?
What organelle organizes spindle fibers during mitosis in animal cells?
What is the Centrioles?
Where and what type of cells does mitosis produce?
What is somatic cells/body cells?
Uncontrolled cell division that can form tumors.
What is cancer?
A tumor suppressor gene often called the “guardian of the genome” because it checks DNA for damage before a cell divides.
What is the p53 gene?
The phase when two nuclei begin forming at opposite ends of the cell.
What is Telophase?
What is the name of the structure where chromosomes attach to spindle fibers?
What is the centromere.
A gene that can cause cancer when mutated and stuck in the “on” position.
What is an oncogene?
What kind of reproduction relies on mitosis?
Asexual reproduction.
The process of programmed cell death
What is apoptosis?
Name all four phases of mitosis in the correct order
Prophase, metaphase, anaphase, telophase
What dissolves to allow chromosomes to move during prophase?
The nuclear envelope/membrane
Depicts whether a cell can move on to divide
What is SA/V ratio?
This cellular structure surrounds DNA in eukaryotic cells but is absent in prokaryotic cells.
What is the nucleus?
