Google? Is This Cancer?
What Is The Term Used To Describe A Tumor Able To Metastasize.
Malignant
What stage is NOT part of interphase?
Cytokinesis
Mitosis consists of many phases, which of these phases does the cell stay in the longest?
Prophase. (Interphase is not apart of mitosis.)
What type of cell has a cleavage furrow?
animal cell
__________ are surveillance mechanisms that halt the progress of the cell cycle if any of the various events involved not working correctly or are not happening in the correct order.
Checkpoints
What is the common term used to describe a tumor that does not metastasize?
Benign
During which of the following phases will a human somatic cell contain the least amount of DNA?
G1 phase
Between which two phases is a cellular checkpoint present in mitosis?
Between Anaphase and Metaphase.
How many chromosomes are present in a human somatic cell during the G2 phase?
46
What is another word for Cellular Membrane?
Semi permeable
Cancer cells exhibit several characteristics. List two of these characteristics that allows us to differentiate them from normal cells.
They are neither density-dependent nor anchorage dependent.
What Cell part disappears during pro-phase?
Nuclear Membrane
During Cytokinesis a cleavage furrow forms in a animal cell. How are plant cells different in this regard?
They form a cell plate.
During what stage of the cell cycle would you expect to have the lowest amount of cellular growth and synthesis taking place?
The M Phase
Who discovered the cell?
Robert Hooke
What are the checkpoints in the cell cycle that cancer cells refuse to follow?
G1, G2 and Anaphase/Metaphase
What reproductive cycle produces somatic body cells?
Mitosis
What are the anchorage points to the further ends of the cell known as?
They are known as asters
When a cell's DNA has become damaged beyond repair, the cell undergoes which of the following processes? (Cell Suicide)
Apoptosis
__________break down various substances, including hydrogen peroxide (H202), fatty acids, and amino acids; common in liver and kidney cells; in plant cells, these modify by-products of photorespiration.
perioxisomes
Malignancy is detrimental to the human body due to the fact that they can spread through lymph nodes and enter other areas of the body. Based on what you already know about cancer why would these aboriginal cells propose a problem?
These cells are able to divide at a alarming rate and lack density dependence as well as anchorage meaning they are able to form tumors putting pressure on nearby organs. This causes a problem due to the fact that it can obstruct blood flow and damage healthy tissues.
Why do cells divide after they get to large?
The volume of the cell increases faster than the surface area. It becomes harder for the cell to transport nutrients and wastes across the cellular membrane.
What does interphase consist of? Be sure to specify what happens in each individual phase.
G1-Cell grows to full size to prepare for division.
S- DNA is replicated.
G2- cell replicates organelles.
Which of the following steps is irreversible in the cell cycle?
I. Transition from prophase to metaphase
II. Sister chromatid separation
III. DNA replication
II and III
Which of the following does not regulate cyclin-dependent kinases (CDK's) to influence a cell's progress through the cell cycle?
I. Cyclin concentration
II. CDK phosphorylation/unphosphorylation
III. Subcellular localization
IV. Controlled cell lysis
IV only
