Mitosis

Genes are what parent passes on to their off spring. The reason that the off spring don’t look identical to the parent is due to a process called crossing over during meiosis.. Meiosis creates new cells that contain different data than that of the parent due to the genes getting shuffled around by cross linking. The chromatids which are parts of the chromosome cross over bits of data making the new cell unique from the parental chromosome. Dividing this way will ensure that the genes will be…

Life goes and comes with different experiences and adventures, as the life of two beautiful sisters. These pair of sisters used to be all the time together, share everything, and have the same stuff, even sharing their own living space. They were called the sisters chromosome. These two sisters were like twins, always together and living in the same nucleus. This was normal for them, as if they had the same genes and the same components that made them be so unified. These two sisters were…

he two processes of nuclear division are similar as in they allow cells to divide and reproduce, but they also have many differences. Meiosis is the type of nuclear division that occurs in sexually reproducing organisms. In meiosis, the diploid number of chromosomes is reduced to the haploid number. Gametes have the haploid number, while zygotes have the diploid number. The homologous chromosomes that appear in the zygote look alike and have the same length and centromere position, but the…

Meiosis starts: DNA Replicates I am going to draw a nucleus with DNA inside it represented with beads as the four pairs of chromosomes. Outside of the nucleus there will be centrioles drawn. This is where meiosis begins and replicates the cell Spindle fibers start to form on the centrioles and chromosome pairs bind together making tetrads. Nuclear membrane starts to dissolve. Nuclear membrane will be drawn in dashed lines. The chromosomes will be homologous pairs with centromere in the center…

To create tissues and organs, there are six basic processes that a cell is required to go through. The six processes include: cell division, cell growth, differentiation, migration, apoptosis and cell connections. Cell division is a cell progressing through the cell cycle in order to multiply. Cell growth is a cell using the nutrient and optimal environment to grow in volume. Differentiation is a cell turning into specialized cells due to different gene regulators. Migration is a cell moving to…

Evaluation: The graph that was produced shows that Whitefish Blastula cells spend the most amount of time in interphase followed by prophase, metaphase, anaphase and finally telophase. Relative time was found by finding the total number of cells in each phase and then dividing it by the total number of all cells counted and finally multiplying by 100. Doing this showed that the cell that takes up the most amount of time is interphase at 71.35%. Although I was unable to confirm the accuracy of…

Cellular manufacturing is an application of Group Technology in which machines or processes have been aggregated into cells, each of which is dedicated to production of a part or product family or limited group of families. Parts with similar processing requirements are identified; these are then placed into logical groups called part families and the equipment requirements for each part family are subsequently determined. A part family is a collection of parts which are similar either because…

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. “Some insects, fishes, amphibians, mollusks, crustaceans, cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually accompanied by a change of habitat or behavior”. (http://en.wikipedia.org/wiki). But this change has been incorporated to human’s life…

cytokinesis. Within nuclear division are two different types: mitosis and meiosis. Mitosis is a form of asexual reproduction in which one diploid parent cell is divided into two identical diploid cells. On the other hand, meiosis is an example of sexual reproduction, in which two diploid parent cells both contribute genetic material to form four haploid cells which each have half the genetic material contained in the parent cell. Mitosis and meiosis are similar in that they both result in the…

In rolling circle replication, a nicking protein called relaxase identifies a specific sequence on the DNA and makes a “nick” or cut at that location. The nick is created by the protein and allows the DNA to unwind and continue the process. Once the DNA opens forming an open complex from there a lagging strand will develop along the 3’ template strand due to the polarity and orientation of the strands. A leading strand will emerge and DNA polymerase enlists nucleotides to pair with the exposed…
