Practice question
Question
Two proteins of molecular weights 1.0 x 10 ⁵ and 1.0 x 10 ⁴ Daltons were eluted from a gel filtration column at 220 ml and 300 ml respectively. The molecular weight of an unknown protein that elutes at 140 ml under the same conditions, will be
Explanation
The principle of quantitative reasoning explains that ratio, percentage and series logic determine correct calculation. Hence 1.00 x 10 ⁶ fits best because it meets mathematical and logical criteria, as documented in authoritative sources on aptitude and reasoning.
