Summarize what happens to chromosomes during the stage of the cell cycle in which the nucleus divides Include the terms prophase metaphase anaphase and telophase?
Prophase: Chromosomes condense into visual forms and nuclear envelope breaks down. Metaphase: Chromosomes pair and line up along metaphase plate(midline) and also attatch to mitotic spindles at centromere. Anaphase: Mitotic spindles attached to chromosomes pull half of the chromosomes to each side of cell. Telophase: Nuclear envelope begins to reform. animal cells: Cleavage in cell occurs which divides cell into two. plant cells: Cell wall forms in the middle of cell to separate the cell.
Five steps of mitosis?
Interphase: Before mitosis begins. Chromosomes are doubled. Each chromosome forms into two chromatids.Mitosis Phase 1 (Prophase): Chromosomes condence from long strands into rodlike structures.Mitosis Phase 2 (Metaphase): Nuclear membrane disolves. Paired chromatids align at the cell's equator attached to spindle fibers.Mitosis Phase 3 (Anaphase):The paired chromatids separate and each chromatid is pulled to the opposit side of the cell.Mitosis Phase 4 (Telophase): nuclear membrane forms around each set of chromosomes, and they condense. Mitosis is complete.Cytokinesis: Animal cell:The cell pinches in two.Plant cell-a cell plate forms and seperates the cell into two at the center.☺Your welcome♥
What are the steps of meiosis in order?
it starts out with interphase, which is where the cell grows, reproduces it genome into two sister chromatids, which attach into tetrads (4 connected chromosomes, two sets of each) and gets ready for meiosis. Meiosis is when the nucleus actually break aparts and it starts with prophase, where the mitotic spindle (think of it as a pulley) starts to form, the nucleus breaks up. In metaphase, the mitotic spindle (made of microfilaments or long spaghetti like proteins) is complete, attached to kinetochores in the centromeres (the attach places of the sister chromatids) or other microfilaments. The spindle then starts to push on other microfilaments in anaphase, elongating the cell and breaking apart the tetrads, sending one sister chromatid to each side. . Telophase is when the new nuclei reform and gets ready to prepare mitosis to make sex cells. Cytokinesis, not part of meiosis but definitely related is when the two cells seperate due to a groove that eventually splits the cell into two. The groove is made by microfilaments tightening like a thread around the middle of the cell. Then the two cells undergo mitosis, splitting the two sister chromatids into four haploid cells. The first part is called meiosis 1 and the second is meiosis 2 (the mitosis part)
How does the appearance of the chromosome change through division?
first it becomes two chromatids, then during prophase, chromosomes condense from long strands into rod like structures. During METAPHASE paired chromatids align at the cell's equation. Then during ANAPHASE the paired chromatids separate and move to the opposite side of the cell. During TELOPHASE a nuclear membrane forms around each set of chromosomes, and the chromosomes decondense.
Will rotating move text from the right side of the cell to the left side of a cell?
Unless you specify otherwise, text you enter in a cell is lined up along the upper-right side of the cell.
What happens to chromosomes during the stage of the cell cycle in which the nucleus divides include the terms prophase metaphases anaphase and telophase?
Prophase: Chromosomes condense into visual forms and nuclear envelope breaks down. Metaphase: Chromosomes pair and line up along metaphase plate(midline) and also attatch to mitotic spindles at centromere. Anaphase: Mitotic spindles attached to chromosomes pull half of the chromosomes to each side of cell. Telophase: Nuclear envelope begins to reform. animal cells: Cleavage in cell occurs which divides cell into two. plant cells: Cell wall forms in the middle of cell to separate the cell.
What is the process in which a cell undergoes to produce two cells?
This process is known as mitosis. The cell cycle consists of the following five stages, but only the last four are part of actual cell division. 1) Interphase - cell grows, prepares itself for cell division, and duplicates it's chromosomes. 2) Prophase - chromosomes (double strands) shorten and thicken. 3) Metaphase - chromosomes line up in centre of cell. 4) Anaphase - chromosomes split, and one of each pair starts being pulled to each side of the cell. 5) Telophase - cell splits. Two new cells are formed, both identical to each other and the parent that split into them. Both have complete sets of chromosomes. Process then returns to interphase.
What are adjacent cells?
Adjacent cells are cells that touch each other. So they are side by side or above or below each other. Cell A1 is adjacent to cell A2 and cell B1.

I want to research cell phones by motorola.?
Have a look at Motorola.com. They have complete specs and side-by-side comparisons available there.
How is plant cell cytokines different from animal cell cytokines?
Animal Cells: Toward the end of telephase the the plasma membrane pinches off along the equator of the cell. The two new cells are separated. Plant Cells: The cell plate is laid down across the cells equator. A cell membrane forms around each new cell, and cell walls form on each side of the cell plate unil the separation process is complete.

How is mitosis transmitted from one cell to another?
It is not. Mitosis is the splitting of a single cell. It is only a portion of the cell's life only acounting for not even 20% of it. It consists of five phases: Protophase, Metaphase, Anaphase, Telophase, and Cytokinesis. Protophase is the process of duplicating a cell's DNA and other organelles in preparation of a split. The Nucleus begins to fade. In Metaphase, the DNA lines up along the centre of the cell as centrioles side on either end of the cell. In Anaphase, the centrioles grab hold of the DNA and split it apart and pull them close. In Telophase and Cytokinesis, the cells begin to become more independant and split their cytoplasm. The membrane forms between them and they become two different cells.
What is telophase and anaphase?
Telophase and Anaphase are stages in Mitosis, which is the non-sexual reproduction of a cell. It's happening in your body right now!Remember the stages like this:ProphaseMetaphaseAnaphaseTelophaseProphase is when the DNA in the nucleus of the cell becomes visible, as it is copying itself, forming homologus pairs. This is obvious under a microscope as a dot in the cell.Metaphase is when the homologus pairs then line up across the cell. the chromosomes are still connected by their centromeres. There are two centrioles on either side of this line at opposite ends of the cell. Spindle fibres coming from these centrioles attatch themselves to the centromeres of the chromosomes, one on either side.Anaphase is when the spindle fibres attached to the centromeres pull apart the homolgus pairs, each taking one chromosome to the opposite sides of the cell.Telophase is when the chromosomes for little nucleuses at either end of the cell. The cell membrane then begins to grow into the cell, splitting them apart.The cell then returns to Interphase, which it is in for most of its time.
