The folding pathways of some proteins require two enzymes that catalyze isomerization reactions such as,

a) Peptide prolyl isomerase (PPI)  catalyzes the elimination of folding intermediates with inappropriate disulfide cross-links

b) Protein disulfide isomerase (PDI) enzyme that catalyzes the interchange, or shuffling, of disulfide bonds until the bonds of the native conformation are formed

c) Peptide prolyl cis-trans isomerase (PPI) catalyzes the interconversion of the cis and trans isomers of Proline residue peptide bonds

d) Peptide prolyl isomerase (PPI) can be a fast step in the folding of proteins that contain some Pro peptide bonds in the cis conformation

Chromosome mutations can be grouped into three basic categories:

I) Chromosome rearrangements

II) Aneuploidy

III) Polyploidy

these mutation alters the number and structure of chromosomes such as,

 a) One or more individual chromosomes are added or deleted

b) The loss of a chromosomal segment

c) A piece of a chromosome might be duplicated, deleted, or inverted

d) One or more complete sets of chromosomes are added

e) In which one or more copies of a DNA segment is produced
