chromosomes. Eukaryotic cells have information processing organelles‚ such as the nucleus which houses most of the cell’s DNA‚ and ribosomes which use information from DNA to produce proteins. In prokaryotes gene regulation begins during transcription. Transcription begins when RNA polymerase binds to the promoter. RNA polymerase then begins to separate the two DNA strands and initiates copying. Once this has occurred‚ a terminator sequence signals the end of the gene. The terminator sequence gets

range from insertions‚ deletions‚ nonsense‚ and even repeats‚ which ultimately can result in a nonfunctional protein. The APC gene produces a protein known as the APC protein that is involved in regulating cell adhesion‚ signal transductions‚ and transcription activation. Park and Vogelstein (2003) stated that‚ “the localization of the APC protein is in the basolateral membrane of the colonic epithelial cells…” When mutations occur within this specific gene‚ it causes excessive proliferation of the colonic
