Peptidases complete the digestion of proteins by turning polypeptides into amino group acids.Although they are active in the gloomy intestine,most enzymes are produced by the pancreas. The pancreas produces the amalyze, trypsin and lipase. The stomachal glands produce pepsin.The wall of the small intestine produces maltase, sucrose and peptides. The thick and muscular stomach wall contains nearly 35 million gastric glands (Roberts and Ingram, 2001). The gastric glands produce a fluid known as gastric juice, which contains pepsin. The amalyse in the mouth dental caries is produced by gastric glands while that found in the small intestine is produced by the pancreas.Pepsin works outstrip in acidic conditions.

Enzyme amalayse is active in the mouth cavity and the small intestine. Peptidases and lipase are active in the small intestine.A chromosome is a long, continuous strand of DNA that contains RNA and a number of different associated proteins. The four types alterations to a chromosome structure are inversion, deletion, duplication, and translocation.

Duplication is the repetition of a part of a chromosome as a head of fusion of a fragment of a homologous chromosome. It is a result of an error in light reflex or mutagens. An example of duplication is the Pallister an syndrome part of the 12 chromosome is duplicated. Inversion is a change in chromosome as a result of a reattachment of a fragment chromosome to the original
