meta phase
The nucleus is not present in this stage of mitosis because the chromosomes form in a line and are preparing to go into anaphase and split the cell.
The organelles used in meta phase are centrioles and microtubles .https://www.youtube.com/watch?v=TKGcfbyFXsw
The nucleus membrane disperses during mitosis.

1.     At the start of metaphase, the microtubules arrange the chromosomes in a line along the equator of the cell, known as the metaphase plate.
2. The nucleus is not visable.
3. Chromosones are visable.
4. Organelles involved are Centrosomes and Microtubules.
5. An interesting fact is Chromosomes are lined up in the middle across the cell’s midsection

Metaphase:

3. The 2nd phase of mitosis; after prophase, before anaphase; stage at which chromosomes attach to microtubules and align down the center of the cells

4. picture below

5. The nucleus is not present

6. Chromosomes are present

7. Centrosomes/ Centrioles & Microtubules

9. The chromosomes line up perfectly down the middle.

Telephase
Telephase is the phase in mitosis is where the cell is connected but still has a connection and is about to break into two different cells concluding mitosis

# data[].attributes.body
1. Anaphase is the phase during mitosis in which the chromatids of each chromosome are pulled apart to opposite sides of the cell and spindles to prepare for cell division.
2. The nucleus is not present because the chromosomes are spreading across the cell.
3. There are chromosomes.
4. No organelles involved since they disappear for this stage of Mitosis except for the centrioles that grow their microtubules into spindle fibers after they connect to the centromeres of the chromosomes.
5. Fact: Ana means up, and Phase means stage, so anaphase means an upward stage.

Telophase - the ending phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to the ends of the cell and forms two nuclei

# data[].attributes.body
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical cells.

3. Prophase, also called the  pre-phase, is the first step during the P-MAT process in Mitosis. During Prophase the chromosomes begin to spiralize (the shortening and thickening of chromosomes) and the nuclear envelope disappears. Then the centrosomes which are duplicated during the G2 phase separate. Finally all of the chromosomes are fully visible and now consist of two chromatids that are located at the centromere which is the region on the chromosome where the microtubules of the spindle attach.

5. The Nucleus is present, but the Nuclear Envelope is not present.
6. Chromosomes are present during this phase.

Prophase is the first step of PMAT or cellular division through Mitosis. During Prophase the DNA condenses and organizes to form the chromosome structure. Because of this, during prophase chromosomes become visible under a microscope. These chromosomes are formed by 2 chromatids joined at the centromere. Mitotic Spindle form in the cytoplasm, and the nuclear envelope disapears.

- Anaphase is when the parts of the chromosome are divided and pulled to opposite sides of the cell.
1. The nucleus is not present in this phase.
2. Yes, chromosomes are present because the chromosome is being divided.
3. The organelles disappear in this stage of mitosis
4. https://www.youtube.com/watch?v=k3ECNH1MSCw
5. In anaphase, the chromosomes divide perfectly.

# data[].attributes.body
Anaphase is the third step in mitosis where the cell lengthens. The spindle apparatus draws the divided parts of the chromosomes to opposite sides of the dividing cell.

5. The nucleus is not present in anaphase. The nucleus disassembles while the chromosomes are split, it will re-form when the cell has successfully divided.
6. The chromosomes are present in anaphase. Two complete sets of chromosomes are drawn to opposite poles of the cell.
7.  The only organelles present are the two pairs of centrioles which are located at opposite sides of the cell.
8. https://www.youtube.com/watch?v=jc4ULAq8iZo
9. Fact: there is no difference in animal or plant cells during this phase. The chromosomes in both types of cells move towards opposite poles.

1. Metaphase is the second step in mitosis. During metaphase the chromosomes align in the middle of the cell along the metaphase plate. Spindle fibers made from centrioles connect to each of the chromosomes in preparation to split them.

2. The nucleus is not present in this stage because it has already been disassembled during prophase.

3. The chromosomes were compacted in the previous stage and are aligned in the middle of the cell. Spindle fibers connect to each of the chromosomes.

4. Centrioles are present in the step. They create the spindle fibers.

5. https://www.youtube.com/watch?v=FykU6Oe5JE8

6. The spindle fibers attach to the center of the chromosome called the centromere.

Telephase - at the end when anaphase and interphase, in which the chromatids or chromosomes move to the  ends of the cell and form two nuclei.

# data[].attributes.body
1. In this stage of mitosis, the chromosomes are pulled away to polar endsand prepare for cellular division
2. The nucleus is not present
3. The chromosomes are present because they are in the process of being divided
4. No organelles were involved

6.  If not corrected in time, mistakes made during mitosis can result in changes in the DNA that can potentially lead to genetic disorders

# data[].attributes.body
In this stage of mitosis, the chromosomes are pulled apart to opposite ends of the cell to prepare for cellular division.  There is no nucleus present due to the fact that the chromosomes are pulling it apart. There are also chromosomes present.
The spindle microtubules are the organelle involved in this phase of mitosis. This organelle directs the movement of the chromosomes.

I learned that anaphase actually doesn't happen in the nucleus but it breaks away from it.

Telophase- this is the ending phase of mitosis when the cell is dividing.
The nucleus is present.
Chromosomes not visible.

It is interesting to see the two cells without the cell wall in the picture below.

While metaphase is occurring, the microtubules (tiny tubes in the cytoplasm in cells) have become attached to the cells spindle fibers (a protein structure that divides the genetic material in a cell).
The nucleus is not present during this stage. Chromosomes however are present during this although it is in its most compacted state. The organelles that are involved with metaphase are centrosomes/ centrioles and spindle molecules.

Interesting fact: Whilst looking through a microscope to find a cell going through metaphase they are very easy to identify, being all the microtubules are lined up in the center of the cell.

1. Telophase is when are almost split but are still barely connected.
2.

The final phase of mitosis.The micro-tubules become even longer, and daughter nuclei begin to form at the two poles of the cell. Nuclear envelopes are formed, the nucleoli reappear, the chromatin of the chromosomes uncoils. Mitosis is now complete: one nucleus has divided into two genetically identical nuclei. Cytokines follows and involves the formation of a cleavage furrow, which pinches the cells in two. There are actually two identical nuclei. The chromosomes are there but aren't visible.

·         First stage of cell division, second in mitosis

·        The chromatin condenses into two rods called chromosomes and it becomes visible

·        Known as chromatin condensation

·        The genetic information has been replicated in interphase so there two identical copies of the chromosome in each cell

·        Twins called chromatids

·        Attached by DNA element centromere

·        The centrosome is the microtubule organizing center in metazoans

·        The centrosomes are separated by molecular motors

·        The nucleolus within the nucleus dissolves

Divided into three sections
1. G1-Gap or growth phase. Cell gains mass and matures.
2. S-Synthesis phase. DNA is copied so that the cell has TWO complete sets of chromosomes
3. G2-An additional phase of growth. Often when mitochondria and chloroplasts proliferate.
