They must occur in the DNA, which is in each cells nucleus. More specifically the nucleolus of the cell. A mutation occurs in an allele, where a base triplet (or a codon) gets transcribed incorrectly.

Answer:
Foods are ingested by the mouth where they are chewed by the teeth and savored by the taste buds present in the tongue. In the mouth, saliva breaks down food into substances that are easier to digest. Subsequently, the pharynx allows food to be swallowed and it pushes the food into the esophagus, the contractions of the esophageal muscle allow the movement of the food through the esophagus and to the stomach where the food is mixed with the juices and are mostly digested. In the stomach nutrients are absorbed. There are particles that are not absorb and they pass to the intestine where other nutrients are transported to the blood, then pass to the large interstinum where there is water absorption and stool formation that are expelled through the rectum.
