The different stages of the mitosis such as interphase, prophase, meta phase, anaphase and telophase of the cell along with the cytokinesis were identified and the stages were differentiated. Introduction: All the living things are made of cells. In a multi-cellular organism, two types of cell division occur: they are mitosis and meiosis. Mitosis or Somatic cell division is the process in which one cell divides into two equal cells with genetic identity. The cell division is necessary for the growth and development of the cells. The transformation of information from one generation to another is called heredity and the genes which are the fundamental part of the chromosome are responsible for the transformation. The chromosomes are present in pairs. Each pair is responsible for a specific part or function in the cell. These chromosomes are distributed equally in new cells during mitosis. Mitosis is thus described as the chromosomal division. This chromosomal division is accompanied by the cytoplasmic division called as cytokinesis. The mitosis along with cytokinesis results in the formation of two daughter cells. This is also called as cell cycle. Cell cycle is the period in which the cell divides and becomes two daughter cells. ...
There are four stages in mitosis. They are prophase, metaphase, anaphase and telophase. (Allen and Harper 2011). Prophase is the first stage of mitosis which is visible. The chromosomes, which are randomly distributed in the cytoplasm condense to form the distinct part. They are held in a single line. Metaphase is the stage in which the chromosome is attached to the centromere through the spindle fibril. The centromeres are connected to the centrioles and the centrioles pulls the chromatids to the opposite directions. This step initiates the cell division. Anaphase is the stage where the chromosomes move to the position of centriole. The chromosomes are seen as complete sets in the opposite side of the cell. Telophase is the last stage of mitosis in which the chromosomes begins to loosen itself from the thicker rigid structure into thin filaments. The division of the cytoplasm starts at this particular point. Materials required: Prepared slide of Allium root tip Prepared slide of white fish blastula. Microscope. Method: 1. The prepared slide of allium (onion) root tip was mounted on the microscope. 2. The 4x objective lenswas used to focus the centre of the slide. 3. The cells undergoing the four stages of mitosis such as prophase, metaphase , anaphase and telophase were identified in the slide using the 10x magnification. 4. Using the 40x magnification in the microscope, the distinct chromosomes and the other cell structures were identified. 5. Similarly, the whitefish blastula slide was mounted on the microscope and the blastula sections were observed using the 4x magnification. 6. Then 40 x magnification was chosen to examine the chromosomes. The cells in each phase of mitosis were identified. Result: For the Onion Root tip: 1.

...a large number of these DNA molecules, in preparation for the transformation of P. pastoris expression system. The vector used in this case was the TOPO vector. After the vector was cloned with the DNA fragment of interest, the plasmids were inserted into E.coli. Plasmids are circular, double-stranded DNA that exists separately from the host’s chromosomal DNA. Despite this, plasmid DNA is still duplicated before every cell division, so that during mitosis, at least one copy of the plasmid DNA goes to each daughter cell. The successive generations of transformed E. coli explains the propagation of the target DNA fragment (Lodish, et al., 2000). A plasmid vector must contain a replication origin (ORI), a drug resistance...

..., 2001) or occurs as a result of DSB formation (Pascucci et al., 2005). Time course experiments conducted by Staszewski et al. (2008) on Chinese hamster ovary cell line exposed to IR and alkylating agents showed the ?H2AX foci to register a fall after reaching a peak value. The authors attribute this to the presence of short-lived DSBs at sites of replication forks that undergo repair. On the other hand, the residual ?H2AX foci that could be detected after a period of extended recovery have been inferred to represent “stabilized” DSBs that are no longer amenable to repair. The residual, unrepaired DSBs are likely to cause chromosal aberrations if cell undergo mitosis, subsequently leading to cell death (Staszewski et...

...with a potential dual role in apoptosis inhibition and regulation of mitosis. Survivin inhibits apoptosis by interfering with the function of caspase-3, caspase-7 and caspase-9 (Shin et al., 2001; Dohi et al., 2004). In addition to apoptosis inhibition, survivin is implicated in the regulation of the mitotic spindle checkpoint and the promotion of angiogenesis, and chemoresistance (Altieri, 2003; Mita et al., 2008). Several mitotic kinases, including the three Aurora kinases, Aurora-A, -B and –C kinases regulate the progression of the cell through mitosis. Lens et al. (2006) have provided evidence to show that survivin acts as a mitotic regulator. It functions as a subunit of the chromosomal passenger...

MITOSISMEIOSIS

...Introduction Cell division or cell multiplication is the process of formation of new or daughter cells from the pre-existing or parent cells. It can be of three types, namely amitosis, mitosis and meiosis. Amitosis is a simple method of cell division which is of common occurrence in many bacteria. Also called the direct cell division it occurs just by elongation and constriction of the nucleus and cytoplasm resulting in two daughter cells. Mitosis is a division of a parent cell into two identical daughter cells having the same number and kind of chromosomes as in the parent cell. Mitosis was first observed by Strasburger (1870) in plant cells. Boveri and Flemming studied it in 1879 in animal cells. The term "mitosis" was coined... by...

...relationship between relative binding affinities and inhibition of cell proliferation by different vinca alkaloids. (reference? The reference is already given at the beginning of the sentence) Vinflunine acts by reducing the microtubule network of interphase cells, inducing G2+M arrest and blocking mitosis at the metaphase/anaphase transition, thereby, leading to apoptosis (Okouneva et al., 2003; Jordan et al., 2008). The presence of significantly higher levels of vinflunine-induced micronuclei in mononucleated cells (MNMono, Table 2) would suggest an increase in the number of cells damaged by vinflunine exposure, that failed to divide. This view is also reinforced by the binucleated cell (BI) data which shows a...

...of the microtubule catastrophe rates. The microtubules are responsible for appropriate position of the nucleus for cell division by the use of the forces originating from the impact of the microtubules on the inflexible cell wall (Fishel & Dixit, 2013, 275). Microtubules are also a very important part of the cytoskeleton during the cell mitosis. Together with the related motor proteins, microtubules form the bipolar mitotic spindle structures which are responsible for the aligning of the sister chromatids beside the metaphase plate (O’Rourke et al, 2014, 10). Together with motor proteins, microtubules are also responsible for the division of the sister chromatids during anaphase. Generation of asymmetric forces by the...

Keywords: bacteria, culture, ‘sell-by’ date Introduction The most common cause of food poisoning is bacteria. These bacteria cause symptoms such as vomiting, stomach cramps, headache, diarrhoea, fever or a combination of the above. Some food poisoning bacteria can cause death. Under the right environmental conditions, that is, warmth, food, moisture and time, bacteria can multiply through mitosis where one can split into two in every 10-20 minutes. Bacteria grow at temperatures between 5 and 63 OC and thrives at temperatures of about 37°C....

Mitosis and meiosis are two types of cell division process. They have the same phases of division, but these processes and their results are significantly different1. During mitotic cell division, each chromosome is divided into two identical chromosomes, which are distributed over the two new cells and formed two diploid somatic cells. During this division in mitosis, the hereditary factors do not change. At meiosis, the division process has two general stages. At the...
