I know almost everything about agarose gel (almost everything that covered in classes)

But i don't know what happens if agorose gel is denser or enuouser

If it is denser, its pores will be smaller

But i don't know how it affects the DNA bands

Will they go farther or closer. Or will bands' lenght become thinner or thicker

Thanks in advance

There is loads of info about agarose gel electrpohoresis found by a simple search on-line, including the Wikipedia entry. I will say that the resolution of DNA bands are affected by a number of factors other than agarose concentration (and there are different types of agarose!), such as the amount of DNA loaded and the comb width.
