The nucleus is what controls the cell and is where near communicable material is located. distributively cell is made up of 46 chromosomes. Chromosomes argon tranquil of deoxyribonucleic acid. Deoxyribonucleic acid is a chemical substance that carries genetic information. Located on the DNA strand be genes which argon inherited from pargonnts. When genes atomic number 18 passed to offspring diseases are in addition sometimes past to earn genetic diseases. Genetic Dis redacts are a mutation in a gene. Mutations are changes in the DNA sequence and toilet happen anytime, from macrocosm a unity cell to being 100 years old. on that point are several quality of genetic mutations that occur, chromosome ab figureities, single- gene disorder, multifactorial disorder, and mitochondrial disorder. Chromosome abnormalities occurs when the chromosome or segment of the chromosome is missing, duplicated, or altered in a bearing that is not normal to it. An abnormal number of chromosomes is when nondisjunction occurs in the testicle and sperm cell. In nondisjunction copies of a chromosome do not in good order separate during division. When this happens two copies of that special(prenominal) chromosome are placed in the energise cell.

When and if this cell is utilize it will come to keep upher with one from another sex cell leaving leash copies of this chromosome. Three copies of a chromosome are called trisomy. In most cases trisomy is shameful however there are some instances where it is allowed and when this happens a have got defect occurs. Down syndrome and Turners syndrome are examples of chromosome abnormalities. Down syndrome is genetic disorder that causes clear-sighted retardation, facial disformations, and decreases muscle tone. The disorder happens on the twenty - foremost chromosome. It is an example of... If you want to get a full essay, order it on our website: Orderessay
