Stages of Mitosis
The stage of mitosis where chromosomes condense and become visible, the nucleus starts to dissolves, and spindle fibers start to form from centrioles
What is prophase?
A chunk of DNA
What is a chromosome?
The 3 (or 2) main phases is the cell cycle divided into
What are interphase, mitosis, and cytokinesis?
The number of cells you started out as (in the very beginning)
What is one?
The meaning of regulation of the cell cycle
What is a system of carefully controlling when cells divide?
The stage of mitosis where two new nuclei form at opposite ends of the cell and chromosomes begin to uncoil back into chromatin
What is telophase?
A section of DNA with instructions for making a specific protein
What is a gene?
The phase a cell spends most of its time in
What is interphase?
The name of the single-cell version of yourself created when one of your father's sperm cells fused with your mother's egg cell
What is a zygote, or fertilized egg?
The result of a breakdown in the regulation of a the cell cycle
What is uncontrolled cell division, or cancer?
The stage of mitosis where spindle fibers attach to the centromeres of chromosomes and pull them into a a line down the middle of the cell
What is metaphase?
The part of a chromosome spindle fibers attach to
What is the centromere?
The first stage of interphase, where the cell grows and makes proteins
What is G1 phase?
The process you underwent to go from a single cell to the trillions you now have in your body
What is mitosis?
Special points in the cell cycle where a cell can either be told to stop or continue its progress in the cell cycle
What are checkpoints?
The stage of mitosis where the cell membrane pinches off in the middle and the cytoplasm divides into two new cells
What is cytokinesis?
An identical half of a duplicated chromosome
What is a chromatid?
The third stage of interphase, where a cell experiences even more growth and continues to synthesize proteins
What is G2 phase?
The process which is the reason you have so many different kinds of cell in your body when you started out with just one single kind
What is differentiation?
The two main kinds of tumors
What are benign and malignant?
The stage of mitosis where chromosomes are pulled apart from each other to opposite ends of the cell by spindle fibers
What is anaphase?
A pair of different versions of the same kind of chromosome; one from your mother, one from your father
What is a homologous pair?
The stage of interphase where DNA is duplicated
What is S phase?
Undifferentiated cells the can become any other cell in the body
What are stem cells?
Programmed cell death (cellular self-destruct mechanism)
What is apoptosis?
