So this is my take or story ( I don't know what sounds better take or story… ya story, ima go with story). So this is my story of the Cell Cycle. So in this story ima go over all of the phases of the cell cycle and some vocabulary words that relate to The Cell Cycle (every time you say “The Cell Cycle” always think of like a big deep confident voice saying it in your head, like Ving Rhames voice. If you don't know who that is, i'll give you a hint, he’s the guy in the Arby’s commercials that says “We Got The Meats”. Well i'm getting off track and I ain't got time to get off track.) I'm going to explain the phases and then translate them as if it was a human being growing up.

This process is split into 4 mini sections. Prophase, Metaphase, Anaphase, and Telophase. Prophase is where the cells Chromatin (the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA). tightens into Chromosomes (A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes). And the Nucleus disappears. Metaphase is where the Spindle fibers (Any of a network of filaments that collectively form a mitotic spindle (in mitosis) and meiotic spindle (in meiosis). It is chiefly involved in moving and segregating the chromosomes during nuclear division). Are forcing the chromosomes to align at the center of the cell. Anaphase is where the chromosomes move away from one another to opposite poles of the spindle. Telophase the final stage in mitosis is where the chromatids (each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA). Or chromosomes move to opposite ends of the cell and two nuclei are formed. Which leads to the final stage Cytokinesis (I know I said telophase was the last, but it isn’t just bare with me please). This is where the cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells. In this stage of Brooklyn's life.

three phases G1, where the cells grows up to double it’s original size, S phase, where the dan is replicated , and G2 ,where the cells finishes it growing and prepares to go into prophase. Prophase is where the cell’s nuclear membrane dissolves. Chromatin tightly coils and condenses into chromosomes. Spindle fiber begins to appear and then the cell goes on to metaphase. During metaphase, the cell’s spindle fibers attach to the chromosomes and the chromosome aline in the middle of the cell.
G1 is the main development period of the cell cycle. In G1, the cell plans to experience cell division. The cell still plays out the majority of its typical capacities, however begins to get greater. The cell then starts to make a duplicate of the cell parts (organelles). It additionally starts to create RNA and orchestrate proteins to prepare to separate.
The same region is also amplified on both chromosomes, however they are different sizes, which are then put into gel
The stages of Meiosis II are: prophase II, metaphase II, anaphase II, and telophase II. Meiosis generates four haploid cells, which begins with the division of one diploid cell. Diploid means having two sets of chromosomes, and haploid means having half the number of genetic information as diploid (or one set). To begin, late interphase is the phase when the DNA in the diploid parent cell is replicated. Then, in prophase I, the chromatin condenses and the chromosomes become visible.

There are two main phases that are found in the cell cycle, they are the following: interphase and mitosis. Mitosis is subdivided into several phases which are prophase, metaphase, anaphase, and telophase. Each one of the phases of the mitosis has a specific duration. In the case of plant and human cells, the
56 (6): 1875–1881). Lag Phase: This is the period immediately after sub-culturing bacterial cells on culture medium. During this phase there is no apparent cell division as the bacteria are adjusting to the new environment, finding sources of food and synthesizing enzymes for metabolism Log Phase: Bacterial cells divide by binary fission and the bacterial population grows exponentially (1, 2, 4, 16, 32 etc.) Stationary Phase: Bacterial cell division cannot continue indefinitely as the cells begin to run out of food and space.
The sister chromatids are pulled towards oppsite poles of the cell. (http://andrewhulse.weebly.com/archive-blog---life-in-room-213206209/archives/01-2014) Telophase:the chormatids are now called chormosomes. The nuclear envelope reforms arounds the two sets of chromosomes to form two new nuclei and in each nucleus the nucleolus reforms. The spindle fibres disappear and the chromosomes become uncoiled, elongated and are no longer visible.
All organisms consist of cells that multiply through cell division. To produce two identical daughter cells, the DNA in each chromosome must be first duplicated (Phase S) after which the two completely identical copies must be accurately segregated to the two daughter cells. (Phase M) These essential steps of life are commonly known as the cell cycle and are the basis of the creation and the sustention of all organisms.
All living things are made up of million and billions of cells. Cells, like everything, have a beginning and an end; they have something like conception, how it is made and death, how it will die. Three scientists of the name Sydney Brenner, Robert Horvitz, and John Sulston have contributed to the biological and medical fields with their discoveries on how the organs develop and on the cell’s death. As everything, there has to be a balance, an equilibrium.
I’ll be discussing stem cells and issues concerning stem cell research and use in the following paragraphs. Stem cells are undifferentiated cells that have the amazing ability to become other cells. This means that a stem cell has the ability to become any type of cell in the body. For example if a person has a heart attack leading to heart damage, stem cells can be used to create new heart

The synaptonemal complex is a protein complex, which can mediate the crossing over among homologous chromosomes (Peoples,T.L. 2002). It consists of three important parts, the lateral element, the central element and the transverse element. During the leptotene stage, the SYCP2 and SYCP3 proteins form axial elements, lateral element and precursors. The SYCP1 protein contains a carboxy-terminal domain and an amino-terminal domain that are necessary for interaction with lateral and central elements, respectively. The SYCP1 from transverse filaments interact with the SYCE1 and SYCE2, which are the central elements of the synaptonemal complex (Ding, Da‐Qiao,
INTRODUCTION To divide, a cell must grow, replicate its genetic material (DNA), and split into two daughter cells. Cells perform these tasks in an organized series of steps that make up the cell cycle. In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. • During interphase , the cell grows and makes a copy of its DNA.
