During colonoscopy, a flexible Fiberoptic or video colonoscope is used to visualize, examine and photograph the large intestine including the anus, the rectum and the sigmoid, transverse and ascending colon. This procedure is most frequently used for cancer screening and for surveillance in patients with previous colon cancer or polyps. In addition, tissue biopsies can be obtained as needed and polyps can be removed and evaluated. Other uses of colonoscopy include the evaluation of patients with diarrhea of unknown cause, occult bleeding, or anemia; further study of abnormalities detected after a barium enema and diagnosis clarification and determination of the extent of inflammatory or other bowel disease. Colonoscopy is contraindicated if the patient has a suspected or documented colon perforation, acute severe diverticulitis or fulminant colitis.
It’s differing from ribose in having a hydrogen atom instead of an OH on one of the carbon atoms
I think answer is D- because when the cell breaks in half it’s not recreating it’s full self and also preventing mutations from happening
Genes close to each other- Strongly Linked genes
Genes on different chromosome- unlinked genes
Genes apart from each other,but on same chromosome- linked genes
Explanation:
Linkage is defined as the tendency of genes located on same chromosome to be inherited together.
Genes located on different non-homologous chromosome are called unlinked genes.
Genes located on same chromosome are called linked genes.
Genes located close to each other are strongly linked as tend to show complete linkage.
Genes located on different chromosome tend to show incomplete linkage.
