definitions
definition of cell cycle
The regular sequence of growth & division that cells undergo.
what is Cytokinesis
The final stage in the cell cycle, in which the cell's cytoplasm divides, distributing the organelles into each of the 2 new cells.
DNA
deoxyribonucleic acid, the material that contains the information that the cell needs to function
Why do cells go through Mitosis?
growth, repair, reproduction, replacement
what is the most important part of cell replication
definition of Interphase
The stage of the cell cycle that takes place before cell division occurs; the cell grows, copies its DNA & prepares to divide
what is the definition of Prophase
first phase of mitosis in which chromosomes condense and become visible and nuclear membrane disappears
Chromatin
Thin strands that contain DNA during Interphase
Sister Chromatid
Identical rods of the the chromosome
what do 2 sister cells always have to have incommon
both having the same amount of chromosome
what is Replication
The process by which a cell makes a copy of the DNA in its nucleus by unwinding and unzipping and takes place in Interphase.
Anaphase
the third phase of mitosis, during which the chromosome pairs separate and move towards opposites ends of the cell
Longest phase of the Cell Cycle
Interphase
Centromere
Holds Sister Chromatids together
what happens if a cell doesn't have the right amount of chromosomes
what is Mitosis
The 2nd stage of the cell cycle during which the cell's nucleus divides into 2 new nuclei
telophase
4th and final phase of mitosis where 2 new nuclei are formed
Phase of the cycle that differs in plant and animal cells
Cytokinesis
Spindle Fibers
Attach to centromeres during metaphase and pull sister chromatids apart
cell renewall can only happen is 2 things which are.
plants, and fungus
what is a Chromosome
Condensed chromatin; contains DNA that carries genetic information .
metaphase
2nd phase of Mitosis: Chromosomes line up in the middle of the cell
Cell Plate
This must form in a plant cell during cytokinesis to help break the cell apart
what shape does a chromosome look like
where in the body does mitosis take place
all over the body, to keep the tissues and organs healthy
