The entire process of cell growth and division is referred to as the:
What is the cell cycle?
What are the two main types of stem cells?
Adult and embryonic
Name the 4 phases of mitosis.
What are prophase, metaphase, anaphase, telophase?
Cytokinesis is the division of the ________.
What is the cytoplasm?
Phase where DNA is replicated (copied)
Uncontrolled cell growth and division leads to this disease.
What is cancer?
This is the process by which stem cells become specialized and take on specific functions.
What is the differentiation?
During this phase, sister chromatids are pulled apart and move to opposite ends of the cell.
What is anaphase?
T or F Mitosis results in 2 identical daughter cells
What is True?
Phase of normal growth and function
What is Gap 1 (G1)?
When a cell fails to pass checkpoints, it may be killed to protect the health of the cells around it. This is referred to as:
What is apoptosis?
This is the condensed form of DNA that is seen during late prophase, metaphase, anaphase, and early telophase.
What are chromosomes?
During this phase, chromosomes are lined up across the middle of the cell.
What is metaphase?
This is a fan-like structure of microtubules that helps separate chromosomes
What is spindle?
Phase of growth to prepare for division
What is Gap 2 (G2)?
In eukaryotic cells, cytokinesis is preceded by nuclear division, aka __________.
What is mitosis?
Once DNA is replicated and condensed into chromosomes, identical copies known by this name are held together by a centromere.
What are sister chromatids?
If a cell completes this phase, it will have two nuclei.
What is telophase?
This is one reason cells divide, then continue to grow indefinitely
What is a larger cell becomes less efficient, or volume grows faster than surface area, placing increasing demands on DNA?
Throughout the cell cycle, cells pass through _________________ to ensure they are healthy and ready to move onto the next stage.
What are checkpoints?
Checkpoints occur throughout the cell cycle to ensure healthy cell growth and division. These checkpoints are controlled by what type of macromolecule?
What are Proteins-cyclins?
If a cell's surface area is 6 cm3 and its volume is 1 cm3 what is its ratioof surface area to volume
What is 6:1?
During this phase, a cell's nuclear membrane breaks down while its DNA condenses into chromosomes.
What is prophase?
It is better to have a Surface area to volume ratio that is larger or smaller
What is larger?
