three functions of cell division
Nucleus
Contains the DNA of the cell
Cytoplasm
Contains the rest of the cell
Ribosome
An organelle in the cytoplasm that makes proteins by reading RNA and joining amino acids.
Nucleotide
The building block of DNA. It is made of a sugar, a phosphate and a base.
A, T, C, G
The letters of the four bases of DNA
Gene
A section of DNA that codes for a protein
RNA
Carries the code from the DNA in the nucleus to the ribosome in the cytoplasm
Cell Cycle
The sequence of events in the cell from one division to the next.
Interphase
The phase of working and growing. The cell makes copies of its organelles and its chromosomes (DNA).
Mitosis
The process that divides nuclear material in cells (DNA).
Cytokinesis
The process that divides the cytoplasm and the rest of the organelles in half. The division of the cytoplasm to form two separate daughter cells immediately after mitosis.
Prophase
The first and longest phase of mitosis, during which the chromosomes become visible and the centrioles separate and take up positions on the opposite sides of the nucleus
Metaphase
second phase of mitosis, during which the chromosomes line up across the center of the cell
Anaphase
the third phase of mitosis, during which the chromosome pairs separate and move toward opposite poles
Telophase
the final stage of mitosis, in which the chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes
Spindle
tiny fibers that are seen in cell division
