Important Parts
Tightly wound bundles of DNA in an “X” shape
WHAT ARE CHROMOSOMES?
The cycle where cells grow and divide
WHAT IS THE CELL CYCLE?
The part of Interphase where the cell grows to maturity and prepares to copy DNA by forming mRNA and histones
WHAT IS THE “G1” PHASE?
The phase of mitosis where the nucleus and nucleolus disappear and chromatin condenses into chromosomes
WHAT IS PROPHASE?
These are the unspecialized cells that have the potential to divide into most other specialized cells in the body
WHAT ARE STEM CELLS?
The relaxed form of DNA found in the nucleus of a cell
WHAT IS CHROMATIN?
The longest phase of the cell cycle where cells grow, do “daily living,” and prepare for division
WHAT IS INTERPHASE?
The part of Interphase where the cell produces a copy of its DNA
WHAT IS THE “S” PHASE?
This is the phase of mitosis where nuclei and nucleoli reappear to enclose the split chromosomes
WHAT IS TELOPHASE?
This is the name given to unregulated cell growth, the results of which are the crowding out of healthy cells and the loss of tissue function
WHAT IS CANCER?
The midpoint of the chromosome where the spindle fibers attach
WHAT IS A CENTROMERE?
The phase of the cell cycle where the nucleus is split into two nuclei, each containing identical DNA
WHAT IS MITOSIS?
The part of Interphase where the cell continues to gather supplies for division as well as creating microtubules
WHAT IS THE “G2” PHASE?
The phase of mitosis where chromosomes are lined up across the cell’s equator
WHAT IS METAPHASE?
Difficulty in transportation, communication, and structural support are reasons for the limitation of this
WHAT IS CELL GROWTH?
The identical sides of the chromosome
WHAT ARE SISTER CHROMATIDS?
The phase of the cell cycle where the entire cell is split into two identical cells
WHAT IS CYTOKINESIS?
The offshoot of the G1 phase where a cell matures but never continues on through cell division
WHAT IS THE “G0” PHASE?
The phase of mitosis where chromosomes are ripped apart
WHAT IS ANAPHASE?
These are materials that are known to possibly cause cancer
WHAT ARE CARCINOGENS?
The (unfortunate) name of the valley that forms and deepens as cytokinesis progresses
WHAT IS A CLEAVAGE FURROW?
The name given to the split cells after complete separation takes place
WHAT ARE DAUGHTER CELLS?
These are the two possible types of the G0 phase
WHAT IS REVERSIBLE AND IRREVERSIBLE?
These are the three parts of the Spindle Apparatus
WHAT ARE CENTRIOLES, SPINDLE FIBERS, AND ASTER FIBERS?
This is the type of cell death that is pre-programmed into the cell
WHAT IS APOPTOSIS?
