All moral rights asserted. Recolouring or alteration of the image is prohibited without permission. Light micrograph of a section through a duodenum, the beginning of the small intestine, which runs from the stomach to the large intestine. It is where digestion begins and nutrients are absorbed into the blood. The interior (lumen, left) is lined with villi, which are folds in the intestinal surface that greatly increase the surface area for absorption. Also within the surface are crypts of Lieberkuhn (red-lined ovoids), which secrete enzymes into the lumen that help to digest the food. Underlying this layer is the muscularis mucosae (thin violet line) and connective tissue (blue). Across bottom are layers of smooth muscle and then circular and longitudinal muscles that contract and relax to move food through the duodenum.

Methyltransferase complexed with DNA, molecular model. The strand of DNA (deoxyribonucleic acid, green and blue) is enclosed by DNA methyltransferase 1 (DNMT-1, green and pink). This enzyme acts to add methyl groups to the DNA, a process called DNA methylation, which can silence and regulate genes without changing the genetic sequence. DNA methylation is also being studied in relation to cancer.
