The arrangement of elements based on their properties
Thepotemich [5.8K]
<span>The arrangement of the periodic table leads us to visualize certain trends among the atoms. The vertical columns ( basically their groups) of the periodic table and they are arranged such that all its elements have the same number of valence electrons. And all the elements within a certain group thus share similar properties and that's about it.</span>

OverLord2011 [107]

Answer:

The A option is the correct answer: Non-native disulfide bonds form after beta-mercaptoethanol is removed, so the protein cannot refold correctly

Explanation:

Beta-Mercaptoehanol is responsible to reduce the four disulfide bonds present in ARNase; Urea deals with non covalente bonds.  In presence of both ARNase is denatured.

If Urea is first removed by dialysis, and later is removed Beta-Mercaptoethanol, the enzyme recovers ist activity.

If Beta-Mercaptoethanol is first removed, disulfide bonds different from native use to be formed.  As a result ARNase is not an active enzyme
