X chromosome

Fragile X. Although it may sound similar to a portion of Area 51, Fragile X, also known as FXS or Martin Bell Syndrome, is a serious condition which affects over 200,000 americans each year. Being a quite common gene disease, FXS is known to affect men more than the opposite female gender. In addition to education and physicality, adolescents with this disease also battle the effects of their condition as well as the challenges they face in everyday life. Over the years, Fragile X has…

the loops contained tiny parts where a protein is called CTCF.Researcher found large parts of gene looped together. There were a lot of experiments that took place in my article talking about looping and folding DNA.They also talk about Y chromosome and X chromosome with the 3-D experiment. Folding happen in cancer cells they can use 3-D maps to help find a cure. This is just some of the experiments they did in the article I…

Does someone that you know have Triple x Syndrome or you want to know about it, well this research paper can tell you all about it. Triple x Syndrome can only affect women, and is created when an additional x chromosome is added to the other two x chromosomes. Triple x Syndrome was discovered by Patricia Jacobs in 1959 from one of her patients who was undergoing premature menopause. It can only affect women and they can be diagnosed with the disease at any age. The only noticeable effect it can…

Diagnosis can also come from a clear, recent patient history and of course, the physical effects from the disease. Additional test are also a good idea for the correct diagnosis such as x-rays to reveal abnormalities within the bones and joints, eye exams to check for the jelly-like substance in the eyes (eye exams can also reveal cataracts), and hearing test to measure the different frequencies of sound. Genetic testing is also available…

small number of boys have a different MECP2 mutation and can have some developmental delay. Rett Syndrome has an unknown etiology, perhaps because of the lack of bulk investigations available. According to Pellock, there is a mutation on the X chromosome which affects the methyl-CpG-binding protein 2 (MECP2). There are also other mutations that can cause atypical or congenial Rett Syndrome such as mutations in the CDKL5 and FOXG1 genes. These cases may be caused by partial gene deletions,…

women is Turner Syndrome. Turner syndrome also known as Ullrich-Turner syndrome, gonadal digenesis, and 45,X, is a chromosomal condition that happens to girls and women. It caused because there is either a complete or partial absence of the second sex chromosome. It is known to occur when all or part of the X chromosome is lost before or soon after the time of conception. Humans have 46 chromosomes containing all of a person’s genes and DNA and they usually have 45. It is a very rare disease as…

disturbed tooth eruption, nerve entrapment syndromes, and growth impairment. Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms. Osteopetrosis can have several different patterns of inheritance. Most commonly, the disorder has an autosomal…

Introduction When analyzing biological processes and development, Drosophila melanogaster is an ideal organism to utilize. Compared to other organisms, the functions of D. melanogaster are easier to manipulate due to its quick sedation time from carbon dioxide. These flies can be sedated in less than ten seconds with a carbon dioxide flow rate of 5L/min. D. melanogaster also produces offspring in a short amount of time (roughly 10 days at 25 degrees Celsius), which makes it a desirable species…

Research into the genetics of deafness has shown that mutations in the CX26 gene, located on human chromosome 13q11, cause non-syndromic recessive deafness (9, 10). Expression of GJB2 has been documented in a variety of cells and tissues. In the cochlea, CX26-containing gap junctions are proposed to maintain K homeostasis by ferrying K away from the hair…

(Reece et al. 2014) The Mitotic (M) Phase occurs in two parts: Mitosis and Cytokinesis During mitosis the DNA of the cell condenses into chromosomes and removed by the mitotic spindle. Mitosis takes place in four stages: prophase, prometaphase, metaphase, anaphase, and telophase. In cytokinesis, the cytoplasm of the cell is split in two, making two new cells. Cytokinesis usually begins just…
