Microtubule

Every cell in the body has a nucleus. The nucleus is the largest organelle and is contained within a membrane. The nucleus contains the body’s genetic material, which directs the activities, like the brain of the cell. This is built from DNA and proteins called histones coiled together forming a fine network of threads called chromatin. When under the microscope the most prominent part of the cell is the nucleus. The most visible structure within the nucleus is the nucleolus, which is where…

According to the cell theory, the cell is the smallest form of life but there are many parts of a cell which allow the cell to do the job it is assigned correctly. An example of a cell would be the animal cell, which is a eukaryotic cell or a cell that contains a plasma membrane. Inside the membrane there are parts of the cell called the organelles. (Animal Cell Structure, 2005) Organelles inside the cell have specific jobs to perform for the cell, organelles include the ribosomes, vacuoles,…

Genetics To Down Syndrome Genetics describes the makeup of our cells, genes, chromosomes, and phenotypes. When there is alter in a gene or a duplication of a chromosome, it can lead to a certain diseases. One of the main diseases known today from a duplication of a chromosome is Down syndrome. John Down first put a name to Down syndrome in 1866, but artifacts from Mexico and Saxon documented some cases of Down syndrome in individuals, and also some were found in paintings of the Renaissance in…

Have your ever missed placed your car keys and went crazy looking for them? This is how people with Alzheimer feel every day. Alzheimer’s disease is a form of dementia that causes memory lost, confusion and difficulty understanding questions (Mnt, Oct). This disease has been around for more than a hundred years and received its name from Dr. Alois Alzheimer. In 1906 Dr. Alzheimer performed a cerebral autopsy on one of his patients that was experiencing memory lost and confusion prior her death.…

motor proteins, dynein and kinesin control the transport of melanosomes into melanocyte dendrites as it is the net sum of cytoskeletal forces on an organelle that regulate intracellular transport. Dynein typically walk towards the minus-end of a microtubule in retrograde transport while kinesin move towards the plus-end in anterograde transport in neurons. The purpose of the article was to determine the role and effect of cytoplasmic dynein in melanosome transport in human melanocytes (1).…

During the initial phase, known as interphase, the mother cell is involved in metabolic activity and preparing for mitosis. Chromosomes aren’t easily identifiable in the cell’s nucleus and the cell might or might not contain a pair of centrioles or microtubules in plants. This is the preparatory phase of cell division. After interphase, chromatin in the nucleus starts to contract in the phase known as prophase. Centrioles start moving to polar ends of the cell and fibrous extensions form from…

Body Planes, Regions, Cavities, and Directional Terms The fundamentals of learning the body in the medical field are body planes, regions, cavities, and directional terms. First up are the body planes, which the definition of a body plane is simply a two-dimensional surface. The dimensions of the body plane are both of length and of width and the body planes are used to describe the different locations that are located in the body or are just used for the point of location. There are three…

1. Why do you think the roots of plants are good for studying Mitosis? In my biased opinion, I believe that the roots are suitable for studying mitosis because plants always undergo mitosis. 2. Why does the root tip of the onion need to be stained? The root tips of the onion need to be stain because they provide more visibility when looking under a microscope. 3. How many phases are in the Cell Cycle? There are five stages of the cell cycle which would be Interface, Prophase, Metaphase,…

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…

Tau is used to stabilise the structures that are crucial to cells internal transport system. These structures known as microtubules are vital to brain functionality and are used for cellular cargo and nutrient transportation all over the neuron (Matsuyama and Jarvik, 1989). However, in Alzheimer’s disease and abnormal hyperphosphorylation form of tau separate from the microtubules causing these structures to collapse (Gong and Iqbal, 2008). The separated forms of Tau combine and create the…
