Question
DNA fragments separated by gel electrophoresis are shown. Mark the correct statement
- Band 3 contains more positively charged DNA molecule than 1
- Band ‘3’ indicates more charge density than 1 and 2
- Band 1 has longer DNA fragment than 2 and 3
- All the bands have equal length and charges but differ in base composition
The correct answer is: Band 1 has longer DNA fragment than 2 and 3
