The Fragile X syndrome and Duchenne muscular dystrophy (DMD) disease comparation

The human genome is split into 23 pairs chromosomes (DNA), which atomic number 18 coiled in a spiral ladder sign through nucleotide hydrogen bases (cytosine-c, guanine-g, thymine-t, adenine-a) (fig1 below). Human cells brook 46 chromosomes (fig 2 below) - 22 pairs of autosomes chromosomes 1 to 22 and two stir chromosomes X and y or X and X depending gender (sex-linked). Within these chromosomes are roughly 30,000 components that controls and construct the electric variety meat in the body. There are everywhere approximately 250 know sex-linked infirmitys, printing every organ system. Of these, 95% affect males as it reflects the presence of the abnormal gene on the X chromosome, which is present in two copies in females and one in males. Males inherit the X chromosome from their take and the Y chromosome from their father. Since this is the case, abnormalities on the X chromosome from the mother will usually unmistakable as a disorder within 50% of her males offsprin gs. Since females have a chromosomal make-up of XX, inheriting an X chromosome with unsoundness transmutations in it loosely will not produce the disease condition. The healthy X chromosome that the female has inherited from her other raise male masks the diseased X chromosome.

The female with one mutated X chromosome would be cognise as a mailman because she tummy pass the mutation onto her children, though she may not be directly blow by it. An X-linked disease could affect a female, in a lower percentage, if her mother is a carrier and the disease affects her father. If her mother and her father are both affected with the disease, she will nigh certainly be afflicted with t he disease as well. patronage these many s! ex-linked diseases, at present antepartum diagnosing can specifically be made in fewer than 40 diseases. These sex-linked diseases of single... If you want to get a salutary essay, order it on our website: OrderEssay.net
