The Cell Cycle/Key Vocab
Interphase
Mitosis
Cytokinesis
Cancer
100
The longest phase in the cell cycle
What is Interphase?
100
What are the three major parts of Interphase?
Gap 1:G1 Synthesis: S Gap 2: G2
100
What are the 4 main steps in Mitosis?
Prophase Metaphase Anaphase Telophase
100
True or False: Cytokinesis is a part of the Mitosis process?
False: It is a process after the Mitosis.
100
Occurs when cell cycle becomes out of control
What is Cancer?
200
Describes the behavior of cells as they grow and divide
What is the Cell Cycle?
200
What is the major function of G1?
growth of the cell
200
What is significant about the length of the process of Anaphase?
It is the shortest phase of mitosis
200
What is different in the process of cytokinesis in animal and plant cells?
The Plant cell forms a cell plate instead of a cleavage furrow in order to separate into to 2 daughter cell.
200
a mass of abnormal cells
What is a tumour?
300
What usually occurs in the process of the cell cycle?
Usually divide into two daughter cells
300
What is the major function of G2?
further cell growth in preparation of mitosis (organelles may increase in number and DNA begins to condense)
300
What happens during the process of Metaphase?
Chromosomes move to the middle of the cell and centrosomes are now at opposite poles
300
Cell Cytoplasm Divides
What is Cytokinesis?
300
a cancerous tumour that has spread from the original location to another part of the organism
What is metastasis?
400
What two major phases are involved in the life of a cell?
1. growth is first major process 2. division is the second major process
400
group of proteins that control the cells progression
What are cyclins?
400
When chromatin begins to condense in G2 phase
What is Supercoiling?
400
Why does a primary tumour form?
Sections of genes may mutate or may be expressed at abnormally high levels
500
long, thin fibers of DNA and protein
What is chromatin?
500
DNA replicates
What is Synthesis?
500
What does the process of telophase prepare the cell for?
Cytokinesis
500
What are sections of genes that may mutate called and and what are they triggered by?
The sections of genes are called Oncogenes and they are triggered by an outside agent referred to as mutagens
