Chromosomes
The cell grows,preforms routine life process, and prepares to divide.
What is interphase?
Second phase of mitosis during which chromosomes line up at the equator of the cell.
What is metaphase?
Third phase of mitosis during which sister chromtaids seperate to opposite poles of the cell.
What is Anaphase?
Last stage of mitosis during which chromosomes uncoil to form chromatin, the spindle breaks down and new nuclear membranes form
What is Telophase?
First stage of mitosis during which chromatian condense into chromosomes, the nuclear envelope breaks down, centrioles seperate and a spindle begins to form.
What is prophase?
Splitting of the cytoplasm to form daughter cells when the cell divides.
What is cytokinesis?
Coiled structure made indies of DNA and proteins containing sister chromatids that is the form in which the genetic material of a cell goes through cell division.
What is the definition of Chromosome?
Region of sister chromatids where they are joined together.
What is the definition of Centormere?
A minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
What is the definition of Centiroles?
Organelle inside the eukaryotic cells that contains most of the cell’s DNA and acts as the control center of the cell.
What is the definition of Nucleus?
Attach to the centermere of each pair sister chromatids.
What is the function of Spindle fibers?
The DNA of a chromosome is encoded with genetic instructions for making proteins.
What happens to chromosomes?
As the centrioles move, a spindle starts to form between them.
What happens to Centrioles?
Fialments that form the mitotic spindle in cell division
What is the definition of spindle fibers?
Control center of the cell
What is the role of nucleus?
each copy of DNA attaches to different parts of the cell membrane.
What is the role of cell Membrane?
These instructions are organized into units called genes.
What is the role of Chromosomes?
Help in the formation of the spindle fiber that seperate chromosomes during cell division
The role of centrioles?
Region of DNA on each eukaryotic chromosome that has town major functions during mitosis
What is the role of Centromere?
Forms a protein structure that divides the genetic material in a cell.
What is the role of spindle fibers
A unique feature of the nucleus is that it disassembles and re-forms each time most cells divide. At the beginning of mitosis, the chromosomes condense, the nucleolus disappears, and the nuclear envelope breaks down, resulting in the release of most of the contents of the nucleus into the cytoplasm.
What happens to the nucleus?
the DNA/chromosomes replicate and one set of chromosomes, with some of the cytoplasm and its contents, goes to each new "daughter".
What is the end result?
What has the most genes code for a single protien?
What is Chromosomes ?
At the end of anaphase each pole of the cell has a complete set of chromosomes.
What is the end of anaphase?
Mitosis
What is cell Divsion?
