Why do dna and rna move toward the positive electrode during electrophoresis?

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).

explanation:

your body is trying to warm itself up. or more precisely, sensors in your skin send messages to your brain to generate heat to your body.

c: warm water flows from the western tropical pacific toward south america. that should be the right answer! hope it .
