Which statement is true about disulfide bonds and protein folding?

#Unit 1. Molecules and their Interaction Relevant to Biology

Disulfide bonds have no influence on protein folding since they only form after the protein adopts its native conformation.
Proteins occasionally adopt nonnative conformations and form improper disulfide bonds that can be reversed by the enzyme protein disulfide isomerase.
The folding of the native conformation is influenced more strongly by the formation of disulfide bonds than by the primary structure of a protein.
If a protein forms an improper disulfide bond it is irreversibly inactivated and must be

In each of the following cases, determine the consequences of a single crossover within the inverted region of a pair of homologous chromosomes with the gene order A B C D in one chromosome and a c b d in the other. There is a two situation of centromere for that gene.

(A) Centromere is not included within the inversion.

(B) Centromere is included within the inversion

Following consequence are resulting are

I - The crossover chromatids consist of a dicentric and an acentric

II- One Cross over product is duplicated for the terminal region contain in A and deficient for the terminal region containing D

III- Both cross over products is monocentric
