Which statement is true about disulfide bonds and protein folding?

#Part-A Aptitude & General Biotechnology

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

Which of the following statement is true?

A) PAM matrices are derived from an evolutionary model whereas the BLOSUM matrices consist of entirely direct observations.

B) Because of BLOSUM matrices have less evolutionary meaning that is why the PAM matrices are used most often for reconstructing phylogenetic trees.

C) BLOSUM matrices are entirely derived from local sequence alignments of conserved sequence blocks, whereas the PAM matrix is based on the global alignment of full-length sequences.

D) BLOSUM matrices are more advantageous in searching databases and finding conserved domains in proteins.
