Down Syndrome Essay

Down syndrome Down syndrome is a chromosomal disorder that is a result of when a person inherits all or part of an extra copy of chromosome 21. This can occur in a variety of ways, the causes of which are unknown. The most common chromosomal abnormality that produces Down syndrome is Trisomy 21, a defect in which an extra or third copy of the chromosome is present in every cell in the body. According to Parenting Magazine the number of Down syndrome births is relatively low for 18-yr-old mothers-1

Down Syndrome in Children Down syndrome is one of the most common and easily recognized genetic disorders. It is caused by abnormal cell division that involves the 21st chromosome pair of the 23 pairs of chromosome found in all normal human cells. There are three types of these abnormalities, which are non-disjunction, translocation, and mosaicism. Ninety five percent of children born with Down syndrome are a non-disjunction type which is three rather than two chromosome 21s. About three to

Down syndrome is a chromosomal condition that affects 1in every 700 kids. Down syndrome is when a child has and extra copy of chromosome 21. Down syndrome has many ways of telling if the child has down syndrome, like physical features. You can also tell if a child has down syndrome based on how they act. There are different ways of obtaining down syndrome. Kids with down syndrome are no different than kids that were born with the normal set of chromosomes, they just act a little different and need

Abstract Down syndrome is an inherited disorder caused when abnormal cell division occurs the outcome is an extra genetic material from chromosome 21. Having an extra chromosome affects the physical appearance of an individual and also causes health issues and delayed development. With Down syndrome being the most common genetic chromosomal disorder and cause of learning disabilities in children, we like to see how the student would interact in a school setting. How would a student with Down syndrome

disorder called Down syndrome. Down syndrome is caused by this person having chromosome 21, which is also called Trisomy 21. There are different things you see in people with Down syndrome such as, different physical and mental traits. This genetic condition varies between each person with this genetic disorder. They all have similar features, but do not look the same. Down syndrome was fist described by John Langdon Down in 1866, but the earliest depiction of someone with Down syndrome was a painting

Down syndrome is caused by a person having three copies of chromosome 21 instead of two copies. Down syndrome is also known by another name called trisomy 21. In the picture above it shows a genetic analysis of a person with down syndrome. If you notice in the picture there are 2 sets of chromosome except for the 21st chromosome set there is a pair of three. This is important to notice because chromosome sets are supposed to be in sets of two. It's a fact that the three chromosomes in set 21 are

Down syndrome, also known as Trisomy 21, was first discovered in 1959 by a French physician named Jérôme Lejeune. He identified down syndrome as a chromosomal condition after noticing that there was a extra copy of chromosome 21 in the individual. Chromosomes are small “packages” of genes that carry hereditary information. They determine how a person will look, how their body functions, and traits they will carry. Normally, the human body contains exactly 46 chromosomes but when down syndrome occurs

own syndrome, also known as Trisomy 21, is a lifelong genetic disorder which is caused by the production of an extra chromosome 21. Most people who have Down syndrome have similar physical features. The average symptoms include mental disabilities and delays in maturing. When this genetic condition is classified as severe, those affected by this disease suffer from serious health issues. The chromosome affected by Down syndrome is chromosome 21. Chromosome 21 is twenty first pair of chromosomes

humans is Down Syndrome, a condition associated with an extra chromosome 21. This condition was first described by British physician, Langdon Down (Web. Down Syndrome, n.d.). Symptoms

Down syndrome has three different types of occurrence, Trisomy 21, Translocation, and Mosaicism. Trisomy 21 is the most common one and it accounts for 95% of all cases. It is a congenital disorder which consists of having a whole extra chromosome in the 21st pair of chromosomes in every cell of the body; the person ends up having 47 chromosomes instead of the usual 46. Down syndrome was named after Dr. John Langdon Down, an English Physician, who, in 1866, was the first ever to describe the characteristic
