Trisomy

Trisomy 21, also cognise as low syndrome, is a chromosomal condition in which in that respect is part of or other sham of the twenty-first chromosome. Some oneness born with Trisomy 21 would shed 47 chromosomes opposed to the norm, which is 46 chromosomes. Down syndrome is the to the highest degree everyday chromosomal disorder. There is no evidence that conjure that it is tie in to the persons race, nationality or well-disposed status. However Down syndrome is statistically more common with honest-to-goodness p arents. This has to do with their increase mutagenic exposures within their fruitful cells. This abnormal extra replicate of the 21st chromosome causes mental deliberation and physical abnormalities such as unique facial structures and skinny growth. With Down syndrome also comes the take chances of certain health concerns, such as congenital titty defects, which may result in early death. Down syndrome lav be analyzed through a test called a karyotype. A karyotype tells you how many chromosomes an separate has and allow for show if there is a duplicate 21st chromosome. As of today the national Association for Down syndrome estimates that one in every 691 children are born with Down syndrome. Inter course consists of three stages, possibility 1, Synthesis and Gap 2. During the gap 1 phase cells grow and build adenosine triphosphate for deoxyribonucleic acid rejoinder.

During the Synthesis stage of interphase, which is the show between the mitotic ingredients, the replication of the DNA takes place. During the gap 2 phase, a cell will prepare itself for the process of cell component known as mitosis. Strands of DNA potpourri chromosomes right forwards cell division t! hrough a process known as meiosis, the DNA has to coil thicken and become denser in order to form chromosomes. Before cells divide they produce a new copy of apiece of their chromosomes. This all happens in the supra mentioned synthesis phase. What happens is each chromosome produces two complete copies which stay conjugate together at their centromeres until the mitosis phase....If you want to get a rise essay, order it on our website: OrderEssay.net
