ANSWERS OPTIONS

The gel has a positive charge at one end and a negative charge at the other.

Because DNA has a negative charge, it will be drawn toward the gel's positive end.

Since RNA has a positive charge, it will be drawn toward the gel's negative end.

Since proteins do not have a negative charge, they must first be treated with sodium dodecyl sulfate before being separated.

Gel electrophoresis is a technique for separating DNA, RNA, or protein mixtures by molecular size in the laboratory. Which of the following statements about the gel electrophoresis procedure is incorrect?
