They carry the genes – the unit responsible for the transmission of the parental characteristics to the offspring and also for passing on essential information with each cell division during the development of the embryo , during the growth of a baby to an adult , and throughout life . The material that makes up the chromosomes is deoxyribonucleic acid (DNA) . Human cell contain 23 pairs of chromosomes , 22 are identical pairs , but the 23rd pairs , the sex chromosomes , are identical only in the females , who have two-xx chromosomes . In males the 23rd pairs contains only one x chromosome and a smaller y chromosome . The sex cells themselves ( the spermatozoa and ova ) contain only half the normal number of chromosome – one of each of the 23 pairs – so that when fertilization take place the full complement of 46 is restored . If this balance disturbed , many congenital defects such as Down s syndrome (mongolism) will be the result , less obvious mutations are also responsible for disorders such as hemophilia and muscular dystrophy. Other examples : Calcium : 8.4-10.2mg/dl Catecholamines Cerebrospinal fluid pressure 70-180mm water volume 100-160ml Ceruloplasmin : 20-46mg/dl Chloride : 98-106mmol/L As well as in : Cholesterol ….. Complement components …. Copper … Cortisol … Creatinine |
