1. mitosis- cell divison in which the nucleus divides into nucei containing the same number of chromosomes.
2. The interphase used to be called the resting phase. Interphase isn’t the resting phase becuase their is lots of metabolic activity.
3. Phrophase- chromatin condneses into chromosomes which are in pairs, centrioles start to split apart & move towards separate poles & nuclear eveolope dissolves. Spindle fibers begin forming.
Metaphase- the chromosome pairs line up at the center of the cell & spindle fibers attach. This pulls the chromosomes, now split apart called the sister chromatids.
Anaphase- Spindle fibers pull the sister chromatids apart. The sister chromatids start to move towards the poles.
Telophase- the sister chromatids reach the poles. A nuclear envolop forms around them. Two cells form. Then cytokinesis occurs.
4. Their are 46 chromosomes in the human body cells. Their are 23 chromosomes in the begging of the prophase. Their are four chromosomes in the daughter cells.
5. Cytokinesis is the process when in which a eukatoytic cell seperates the chromosomes in its cell nucleus, into two identical daughter nuclei. Cytokinesis happend at the end of the cycle.
6. A chrosome is an organized structure of DNA & protein. It is a single peice of coiled DNA containing many genes regulator elements. A chromatid one amond the two identical copies of DNA making up a replicated chromosome, which are joined at their centromeres for the process of cell divison.
7. Centromeres are that attach sister chromatids. They are usually located in the center of middle of the chromatids.
8. Spindle fibers are responsible for moving chromosomes to the center of the cell during metaphase & across the cell during Anaphase. Their attached & centromeres of chromosomes.
9. Cleavage furrow in animal cells, a cleavage furrow in animal cells, a cleavage furrow on the outer surface indicates that two cells are forming. Cell plate: plant cells form a cell plate that seperated 2 new cells.
10. Cancer is when cells overly reproduce. Some treatments for cancer are chemotherapy,radiation,therapy, & clinciccal trails.

2. The resting stage of the cell cycle is interphase why the cells are not resting because its
3. prophase-the chromosomes become visible and the nuclear membrane begins to break down, spindle fibers also start extending from both poles of the cell.
metaphase- the duplicated chromosomes become aligned in the center of the cell.
anaphase-the stage of mitosis in which the duplicated sets of chromosomes separate and two identical groups move to opposite poles of the cell.
telophase-is when a nuclear membrane is formed around each new group of
4. 46 chromosomes are in a human body cell.46 chromosomes before prophase begins. 23 chromosomes when the two daughter cell once divides.
5. The process of cytokinesis is the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
6.the purpose of spindle fibers is aggregates of microtubules that move chromosomes during cell division. they are attached to chromosomes atopposite ends of the poles during metophase which creates the chromosomes to split. they attached to the chromosome by by the pulling apart movement required to make two new daughter cells. spindle fibers attach to the opposite ends of the poles during metophase which creates the chromosomes to split. this process of splitting is also known as binary fission
7.The purpose of centromere is proteins that attach sister chromatids together
8. What is found on the chromosomes or chromatids is DNA.

2. What is the resting phase of the cell cycle called? Explain why this stage is really not resting.
Interphase – comprises about 90% of the cell cycle.
The cell is growing in this stage not resting – protein synthesis, metabolic activities, and DNA synthesis.
It is made up of 3 phases:
1 – G, phase
2 – S, phase
3 – G2, phase
3. List the stages of Mitosis and explain in detail what occurs in each stage.
-Prophase – this is when centrioles move apart, the spindle fibers form and attach from centrioles to centomeres by kinetochores, and the nuclear envelope fragments and disappears.
- Metaphase – this is the shortest phase. The centrioles are at opposite ends of the cell and are attached with aster fibers, the chromosomes then move to the metaphase plate.
- Anaphase – this is when the Centromere uncouple and spindle fibers shorten. The sister chromatids separate and move apart. After separation, chromatids are now called chromosomes.
- Telophase – the cleavage furrow develops in animal cells (Cytokinsesi begins). The cell plate develops in plants and the nucleaus appaears. The nuclear membrane reappears, the chromosomes uncoils and in the end two genetically identical nuclei are present.

1. Mitosis is the process of cell division where a cell splits its chromosomes into two identical cells
2. Interphase. The nuclei is working to replicate the DNA and make proteins.
3. Interphase – organelles in the cell double in number, the DNA replicates, and protein synthesis occurs.
Prophase – during prophase the nucleoli disappears, chromatin fibers become tightly coiled and chromosomes become visible. the mitotic spindle, forms between the two pairs of centrioles as they migrate to opposite poles of the cell
Metaphase – Centriole pairs are at opposite ends of the cell. The chromosomes come together on the metaphase plate and are aligned by polar fibers coming from the cell end or poles. Kinetochores develop at the centriole and kinetochore fibers attach to each one. Kinetochore fibers and the polar fibers make up the spindle.
Anaphase – anaphase starts when the paired centromeres of each chromosome move apart. Now, the chomatids are chromosomes. The poles of the cell move farther apart and each one has the same number of complete chromosomes.
Telophase – the polar fibers stretch out and nuclei begin to form at each pole where the chromosomes are. Nuclear envelopes form and the nucleoi reappears. Now the two cells have identical material like the parent cell and cytokinesis starts. Cytokinesis is where the cytoplasm is divided and this makes the two cells.
4. Each cell has 23 pair. 46 pair. 23 pair in each daughter cell.
5. Cytokinesis is the dividing of the cytoplasm. Cleavage is the process that divides the cell by a cleavage furrow appearing and then gets deeper until it cuts the cell in two pieces.

1) Mitosis is the process by which a cell separates the chromosomes in its cell nucleus into two identical sets in two nuclei. It is generally followed immediately by cytokinesis, which divides the nuclei, cytoplasm, organelles and cell membrane into two cells containing roughly equal shares of these cellular components.
DNA
2) Interphase….it is a period of diverse activities that occur prior to the cell splitting.
3) Prophase, Metaphase, Anaphase and Telephase. Prophase – chromosomes become visible and cell starts breaking down. Metaphase, duplicated chromosomes become aligned in center of the cell. Anaphase – duplicate sets of chromosomes separate and move to opposite ends of the cell. Telophase – cytoplasm divides and and a new nuclear membrane is formed
4) Human cells – 46 chromosomes. Beginning of prophase, 23 pair. Daughter cells there are 46 chromosomes or exactly what we began with.
5) The process by which a cell divides into two daughter cells.
6) Spindle fibers help in the attachment of chromosomes…they attach at the centromere.
7) Structure in a chromosome that holds together the two chromatids. It is the point of attachment to the structure that pulls the chromatids to opposite ends of the cell during cell division (see mitosis). During the middle stage of mitosis, the centromere duplicates and the chromatid pair separates, each chromatid becoming a separate chromosome. Thus, when the cell divides, both daughter cells have complete sets of chromosomes.
9) Cleavage furrow is the indentation that begins the process of cleavage, by which animals undergo cytokinesis.A cell plate is a partition formed during cell division in plants that separates the two daughter cells.
10) Cancer is when cells go crazy and over reproduce….chemo-therapy, radiation, surgery are the common types of treatment.
