Does increasing or decreasing the density of agarose gel in electrophoresis separate similar sized fragments?
Adjusting the percentage of agarose will not help separate similar sized fragments.
Large fragments are separated using agarose at a low density, while smaller fragments are separated using agarose at a high density.
However, if two fragments have similar sizes, varying the agarose percentage won't do much to improve the separation; instead, you'll need to change the voltage and/or run time. For example, extending the gel's length or decreasing the voltage will improve the separation of similar-sized fragments.
You can make minor changes to the buffer's composition and the amount of material loaded to further enhance separation.

Changing the density of agarose gel does not affect the separation of similarly sized DNA fragments in electrophoresis. The separation is primarily determined by the size of the DNA fragments and the strength of the electric field applied during electrophoresis.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
