#Part-A Aptitude & General Biotechnology
  1. They are linear molecule composed of a centromere,telomeres and a replication origin termed ARS element.
  2. It is digested with restriction enzymes at the SUP4 and Bam HI sites separating the telomere sequences.
  3. It produces four arms and the foreign genomic DNA is fragmented.
  4. They are replicated in yeast cells and the external cell wall of the yeast needs to be removed to leave a spheroplast.

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

Which of the following combinations is correct about protein folding pathways?
