Question

If a protein subunit has a molecular weight of 50 kDa, how would its relative mobility compare to a 25 kDa subunit in SDS-PAGE?

Accepted Answer

The 25 kDa subunit will have higher mobility.

Answer

The 50 kDa subunit will have higher mobility.

Answer

Mobility cannot be determined from molecular weight.

Answer

Both subunits will have the same mobility.
