How does the porosity of a rock affect its permeability?

how many pores or holes in a rock let more things in depending on how many pores/holes it has. think of it like skin. the bigger your pores the more dirt seeps through

the porosity makes it more or less permeable

Explanation:

Porosity is a measure of how much of a rock is open space. This space can be between grains or within cracks or cavities of the rock. Permeability is a measure of the ease with which a fluid (water in this case) can move through a porous rock.

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).
