Question

Why is the relationship between the log of molecular weight and relative migration in SDS-PAGE considered linear?

Accepted Answer

Because the migration distance is inversely proportional to the log of the molecular weight

Answer

Because the migration distance is independent of the molecular weight

Answer

Because the migration distance is directly proportional to the molecular weight

Answer

Because the migration distance is directly proportional to the square of the molecular weight
