There are many reasons why I decided to choose oculocutaneous albinism to write about, from the praise albinos get in the fashion industry to the hurt and horrible mistreatment from some African towns. It has always been my interest on how an affected person became the way they are now. From the normalcy of their speech, activity and functions but the difference of milky white skin and colorless hair. Skin color has never been an issue for me but to see someone with albinism peaks my interest…

anaphase, and telophase. Mitosis is comprised of prophase, metaphase, anaphase, and telophase. In prophase chromosomes compact and coil, each chromosomes consists of a pair of sisters. In this phase the nucleolus disappears and stops making ribosomes. The second stage is metaphase. This is a very brief stage and it's where all the chromosomes line up in the middle of the cell and each chromosomes attaches to a spindle fiber at its chromere. The…

individuals. With DNA being so vital to everyday life it has several functions. One function is being the creator of chromosomes in our body. Chromosomes are groups of DNA that are tightly coiled in together. Humans have 23 pairs of chromosomes that make up our genetic mutation. For example, if a person is born with an XY chromosome that will be born a male, if they’re born with a XX chromosome they will be born a female. These chromosomal codes help scientist see and predict genetic mutation…

happens when the structure of the gene changes. Making a version that may be transferred to future generations when there’s an alteration of a single base unit in the DNA or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Alexandria’s Genesis is a recessive gene that affects the color of the eyes, as well as multiple body parts. It causes the eyes to turn from blue or grey to purple, six months after birth. And the shade of the eye color to darken during…

The Effects Of Treacher Collins Syndrome Treacher Collins Syndrome is a rare incurable genetic disorder that most often affects the jaw, cheekbones, eyes, chin, and ears. It was identified dating all the way back to Ancient Rome, however, research as to what exactly it was and the causes of TCS was not studied until the 1800s by an English ophthalmologist named Edward Treacher Collins. In 1884, he began an internship at the Royal London Ophthalmic Hospital, a position which later was turned…

I. Introduction to The C-Value Paradox C-Value is defined as “the amount of DNA per haploid cell or the number of kilobases per haploid cell at any given time” (Swift 1950). The C-Value Paradox states that C-Value or genome size does not always equal the number of genes contained within the genome or complexity of the organism. Order of magnitude is when more DNA than what is necessary to encode for proteins. The prokaryotic genome is much simpler than the complex genome of the eukaryote yet…

via the spindle microtubules and pull in opposite directions (Nelson Education, figure 9.8, page 186). In other words, centrioles create microtubules from the centrisome that will become mitotic spindles; these spindles will become attached to chromosomes via kinetochores to produce movement during the cell cycle. 2) The cell plate and cleavage furrow describe the two different processes involved in cytokinesis (the division of cytoplasm). In animal cells, furrowing begins when the midpoint…

The genetic disorder of Progeria is a very rare disease that it does not occur often.Most of the time the genetic disorder of Progeria is not inherited.The genetic disorder is a progressive genetic disorder that cause children to age rapidly. The genetic disorder causes some very serious symptoms. Some symptoms are slow growth and hair loss, they begin in the first year or two of life. They might also have a short stature, underdeveloped jaw, wrinkled or dry skin. They also tend to lose…

daughter cells that are genetically identical to their mothers and have two sets of chromosomes. Mitosis produces 2 diploid cells. Both mitosis and meiosis are processes of cell division. They have the same steps for cell division, prophase, metaphase, anaphase, and telophase. The stages of which are interphase, prophase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope breaks down. The centrioles near the nucleus begin to…

Wilson disease is a recessive inherited disorder. It occurs at birth, but symptoms of the disease do not appear till the ages of 6 through 40 and is caused by a large accumulation of copper in the body. An indication of the disease is a deep copper colored ring around the edge of cornea and the most common medical consequences of Wilson disease is liver disease because the liver is what eliminates the absorbed copper when we consume food and turns it into bile so the copper levels in our body…
