Letʹs say that a hypothetical submersible robot was used to collect samples of sedimentary rock from the sea floor along the section illustrated. The robot moved back and forth along the transect, collecting first from site A, then site III, then site B, then site II, and lastly site D. Assuming that sedimentation has occurred at a constant rate along the transect over the past million years, rearrange the sites mentioned above on the basis of the thickness of the sediments overlying the igneous rock, from thickest to thinnest.

Which of the following is correct regarding the β turns

(1) In Type I β turn i+1 lies in RHH region while i+2 lies near BS region

(2) In Type II β turn i+1 lies in BS while i+2 lies in below LHH

(3) In Type I’ β i+1and i+2 in near LHH which virtually not allowed region for most of amino acid except Gly

(4) In Type II’ β i+2 lies at 00 psi and i+1 in lower right region both i+2 and   i+1  must be Gly
