Agarose gel electrophoresis is suitable for ALL DNA.
Check the answer for How do you make an electrophoresis gel?
For larger molecules like proteins we use polyacrylamide gel electrophoresis (PAGE). For smaller pieces like DNA we use agarose gel electrophoresis
agarose helps in the separation of DNA bands by controlling the pore size of agarose gel
No, the agarose gel is just a polysaccharide.

to vizualise DNA after Agarose gel electrophoresis
Agarose is used in gel electrophoresis to separate nucleic acids (like DNA) by size, charge an other physical properties. Gel electrophoresis uses an electrical current to make particles move. For example, DNA is negative, so it'll travel towards to positive electrode of the gel box. Agarose has small pores through which a DNA can travel. Bigger fragments of DNA travel shorter distances, because it takes longer for them to navigate through the pores of the agarose gel. Identically sized pieces of DNA will travel the same distance, which is why you get bands (DNA with loading dye) after you run a a gel.
Agarose gel electrophoresis is the easiest and most common method used in biochemistry and molecular biology in separating DNA or RNA molecules according to their size.
