On what basis does gel electrophoresis separate dna segments

Gel electrophoresis is a technique used to separate DNA macro-molecules or fragment base on their size and charges. During separation, the DNA fragment will travel through the gel in different direction and at different speed base on their size and charges. However, the movement of nucleic acid in gel is usually influenced by size and conformations, gel concentration, buffer conditions.

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.
