Which organs perform both mechanical digestion and chemical digestion of food?

The organs that perform both the chemical and the mechanical digestion are the mouth and the stomach. Both these organs are one of the initial organs of the digestive tract. The mechanical digestion in the mouth takes place via chewing. The chemical digestion starts in mouth as a result of the enzymes amylase and lipase. The mechanical digestion in the stomach occurs by churning and the chemical digestion is done by protease enzymes.

Hence, the answer is 'mouth and stomach'.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).

to this answer it would be edge enhancement
