PMAT/Mitosis
What happens during Prophase?
Chromatin coil up to form Chromosomes, Two sister chromatids have identical DNA- nucleus disappears, spindles form
How many daughter cells are formed as a result of Cytokinesis
Two daughter cells
What happens in the G1 phase
The major period of cell growth; new organelles are being made
What is caner
An uncontrolled cell growth
What is the G0 phase
A period in which cells do not divide or grow, known as the "resting" stage
What is Metaphase
Chromosomes align in the middle of the cell, chromatids attach to spindle fibers
What happens during Cytokinesis
Cytoplasm divides, two daughter cells are formed
What happens during the S phase
DNA synthesis or replication occurs. Beginning of S phase, chromosomes is composed of one coiled DNA double helix chromatid. At the end, two sister chromatids are made
A super-dividing cell that form masses are known as what
What is a tumor
What are benign tumors
A tumor that is not cancerous, cells do not spread to other parts of the body
What is Anaphase
Sister Chromatids split apart to opposite poles
When does Cytokinesis occur
After Telophase
What happens in the G2 phase
Cell undergoes a period of rapid growth for mitosis by producing all the enzymes that the cell will need in order to divide
What triggers the cell at the checkpoints to continue dividing
What is a growth hormone
What are Malignant Tumors
A cancerous tumor that destroys healthy tissue and spreads to other parts of the body
What is Telophase
Chromatids reach opposite poles. Spindle break down, nucleolus reappears and new nuclear envelope forms-new membrane forms as a result
Where does Cytokinesis occur
In the Chromatin
What happens in the M phase
Mitosis(PMAT) chromosomes line up and eventually turn into two identical daughter cells
What is contact inhibition
It is a regulatory mechanism that functions to keep cells from growing into a mass form of cells
What causes cancers to happen
A mutation within the cells that cause them to uncontrollably divide without warning
What is Mitosis
Cells period of division; two daughter cells are formed in which both contain complete set of Chromosomes
Why does Cytokinesis differ between plant and animal cells
Plant cells use a cell plate and animal cells use a pinch
This whole process is also called
What is interphase
Where does contact inhibition occur
It occurs everywhere
What are the two types of Reproduction and what is the difference
Asexual and Sexual
Asexual is reproduction by a cell duplicating its genetic material
Sexual is when two parents produce offspring that differ genetically from each parent
