Students subjected three sаmples оf five different mоlecules tо gel electrophoresis аs shown in Figure 1. The three lаnes of the gel are numbered 1, 2, and 3 for each of the three samples. Along the left side of the gel, from top to bottom, are the letters A, B, C, D, and E, representing the positions of the five molecules in the samples. A plus symbol is above the top of the gel, and a minus symbol is below the bottom of the gel. Open rectangles representing the sample loading wells are located in each lane, in a horizontal position between the letters B and C. Black rectangles in each represent the molecules in the samples. The data are as follows. In lane 1, there is a black rectangle at position A and a second black rectangle at position B. In lane 2, there is a black rectangle at position C and a second black rectangle at position D. In lane 3, there is a black rectangle at position E. Figure 1. Gel electrophoresis of three prepared samples Which of the following statements best explains the pattern seen on the gel with regard to the size and charge of molecules A and B?
