In SDS-PAGE, the protein sample is first treated with a oxidizing agent and then with anionic detergent followed by fractionation by electrophoresis None of these fractionated by electrophoresis then treated with an oxidizing agent followed by anionic detergent. treated with a reducing agent and then with anionic detergent followed by fractionation by electrophoresis TRUE ANSWER : ? YOUR ANSWER : ?
The subunit molecular weight as well as the number of subunits in the quaternary structure can be determined by combining information from (a)and (b) gel filtration chromatography SDS-PAGE electrophoresis isoelectric focusing TRUE ANSWER : ? YOUR ANSWER : ?
In a native PAGE, proteins are separated on the basis of net positive charge net charge and size net positive charges size net negative charge TRUE ANSWER : ? YOUR ANSWER : ?
Proteins can be visualized directly in gels by none of these using electron microscope only measuring their molecular weight staining them with the dye TRUE ANSWER : ? YOUR ANSWER : ?
In isoelectric focusing, proteins are separated on the basis of their size relative content of negatively charged residue only relative content of positively charged residue only relative content of positively and negatively charged residue TRUE ANSWER : ? YOUR ANSWER : ?
Proteins are separated in an SDS-PAGE experiment on the basis of their molecular weight positively charged side chains different isoelectric points negatively charged side chains TRUE ANSWER : ? YOUR ANSWER : ?
In an SDS-PAGE All of these proteins have the same charge-to-mass ratio smaller proteins migrate more rapidly through the gel proteins are denatured by the SDS TRUE ANSWER : ? YOUR ANSWER : ?
