It doesn't matter that they are fish cells.\nThey will look the same as these stages in any other cell except there will be a different number of chromosomes

When a cell divides you get a new cell. There are actually four main stages of cell division. They are:\nProphase\nMetaphase\nAnaphase\nTelophase.\n\nIf you want more information, I would suggest trying Wikipedia, or your local library.

The following quote is from \n\nhttp://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=3607844&query_hl=6&itool=pubmed_docsum\n\n"prophase lasted 4.8 hr; metaphase, 0.2 hr; anaphase, 0.06 hr and telophase, 3.3 hr, while the interphase lasted 5.4 hr. In accordance with this, the duration of the whole mitotic process was 8.4 hr."

try this one, if the link does not work, put mitosis and drawing in Google.

I don't have any picutres for you to look at, but I can give you an explanation.\nanimal cells are going to be more rounded, and plant cells are more rectangular.\nRemember: PMAT, these are the phases of mitosis\nProphase-the chromatin begins to condense into chromosomes and the nucleus begins to break down.\nMetaphase-The Chromosomes line up or Meet or "MET" at the cellular equator\nAnaphase- The chromosomes are pulled apart at the centromere\nTelophase- The chromatin decondenses and the neclues reforms\nAlso, the diff. between animal and plant cells....\nAnimal cells have a cleavage furrowl like a figure-8.\nPlant cells build a cell plate in between the separated chromosomes\nMitosis results in two daughter chromosomes.

Stages of Interphase\n\n    * G1 phase: The period prior to the synthesis of DNA. In this phase, the cell increases in mass in preparation for cell division. Note that the G in G1 represents gap and the 1 represents first, so the G1 phase is the first gap phase.\n\n    * S phase: The period during which DNA is synthesized. In most cells, there is a narrow window of time during which DNA is synthesized. Note that the S represents synthesis.\n\n    * G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase. The cell synthesizes proteins and continues to increase in size. Note that the G in G2 represents gap and the 2 represents second, so the G2 phase is the second gap phase.\n\n    * In the latter part of interphase, the cell still has nucleoli present.\n\n    * The nucleus is bounded by a nuclear envelope and the cell's chromosomes have duplicated but are in the form of chromatin.\n\n    * In animal cells, two pair of centrioles formed from the replication of one pair are located outside of the nucleus.

False, they line up in the middle of the cell during metaphase. Anaphase is right after that when the mitotic spindles begin pulling the sister chromatids to opposite ends of the dividing cell.

interphase: the nucleolus is visible, cell engaged in metabollic activity, ceirtainly a pair of centrioles.

During the metapase of mitosis.\n\nHere's a picture that should help you out!!\nhttp://www.uhh.hawaii.edu/~ronald/392/Mitosis.JPG

hi, i work 4 a book company, and 1 of our regular books is on cell and molecular biology, if you email me, i can probably give you an answer on exactly what ur question is.

telophase...it's basically the reverse of prophase.

Prophase I\nIn the leptotene stage, the cell's genetic material, which is normally in a loosely arranged pile known as chromatin, condenses into visible threadlike structures. Along the thread, centromeres are visible as small beads of tightly coiled chromatin. Recall that centromeres are connection sites between sister chromatids, which are not yet distinguishable. As the chromatin becomes progressively ordered and visible, homologous chromosomes find each other and bind together. In this process, called synapsis, a protein structure called the synaptonemal complex attaches the homologous chromosomes tightly together all along their lengths.\n\nThe zygotene stage sees the completion of synapsis. The paired homologous chromosomes are said to be bivalent. They may also be referred to as a tetrad, a reference to the four sister chromatids. During this stage, one percent of DNA that wasn't replicated during S phase is replicated. The significance of this cleanup act is unclear.\n\nThe pachytene stage heralds crossing over. Nonsister chromatids of homologous chromosomes exchange segments of genetic information. Because the chromosomes cannot be distinguished in the synaptonemal complex, the actual act of crossing over is not perceivable through the microscope.\n\nDuring the diplotene stage, the synaptonemal complex degrades. Homologous chromosomes fall apart and begin to repel each other. The chromosomes themselves uncoil a bit, allowing some transcription of DNA. They are held together by virtue of recombination nodules, betraying the sites of previous crossing over, the chiasmata.\n\nChromosomes recondense during the diakinesis stage. Sites of crossing over entangle together, effectively overlapping, making chiasmata clearly visible. In general, every chromosome will have crossed over at least once. The nucleoli disappears and the nuclear membrane disintegrates into vesicles.\n\nDuring these stages, centrioles are migrating to the two poles of the cell. These centrioles, which were duplicated during interphase, function as microtubule coordinating centers. Centrioles sprout microtubules, essentially cellular ropes and poles, during crossing over. They invade the nuclear membrane after it disintegrates, attaching to the chromosomes at the kinetochore. The kinetochore functions as a motor, pulling the chromosome along the attached microtubule toward the originating centriole, like a train on a track. There are two kinetochores on each tetrad, one for each centrosome. Prophase I is the longest phase in meiosis.\n\nMicrotubules that attach to the kinetochores are known as kinetochore microtubules. Other microtubules will interact with microtubules from the opposite centriole. These are called nonkinetochore microtubules

if you're studying a section on vocab. or a step by step process make up a song! it's the easiest way to study b/c information's easier to memorize when set to music, and it doesnt take that long (for me anyway). for my biology class i made a song about mitosis. \n\n(sung to the tune of Waiting by Green Day)\n\nBefore, Mitosis occurs\nInterphase, has steps called G1\nG2, S phase and replication\n\nOf Chromosomes to make the daughter\nCells of, the parent cell\nProphase; chromatids join and become one.\n\nCentrioles, separate to make asters\nCentromere is where, chromosomes,\nAre held with spindle fibers.\n\nWell we’re so much closer to, another pair of cells.\nNext phase!\n\nDuring, Metaphase cells meet\nAt the, equatorial plate\nAnaphase, each pole gets a new set of genes\n\nIn Telophase, chromatin mark\nThe end of nuclear division\nThe nucleus and membrane form once again\n\nWell we’re getting closer to another pair of cells\nNext phase!\nA furrow forms between the cells\nSplits organelles\n\nWell we’re so much closer to another pair of cells\nNext phase!\nA furrow forms between the cells\nSplits organelles\n\nCytokinesis makes a\nCell plate in between plant cells\nTo make, cell walls for each daughter cell\n\nCell cycle is completed\nEach cell, now has it’s own set\nOf chromatin; made up of histones and DNA\n\nThe Cell…\nBetter thank somatic cells.\n\nlol...i still remember it.

G1 - chromatin\nS - chromosomes\nG2 - chromatin\nMitosis - chromosomes (the chromosomes become less condensed in telophase though)\nCytokinesis - chromatin\n\nDuring all three subphases, the cell grows by producing protiens and cytoplasmic organelles such as mitochondria and endoplasmic reticulum.  However, chromosomes are duplicated only during the S phase.  Thus, a cell grows (G1), continues to grow as it copies its chromosomes (S), grows more as it completes preparations for cell division (G2), and divides (M).  I'm guessing cell growth is fastest in G1 but im not sure, so dont quote me.\nHope I helped =)
