g In the sliding filament assay, actin filaments are fluorescently labeled to . promote actin filament adhesion to the glass slide promote actin filament interaction with the myosins increase myosin ATPase activity make the actin filaments visible under a fluorescence light microscope. All of these

what's the question ?

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:

instead of copying and pasting things off of tests or work done on computer which im sure you did, try and read over the question carefully
