Hydrolysis of the bound GTP accompanies disassembly of the SRP and SRP receptor and initiates transfer of the nascent chain and ribosome to a site on the ER membrane, where translocation can take place.

Nomograph for the determination of the relative centrifugal fi eld for a given rotor
speed and radius. The three columns represent the radial distance (in mm), the relative
centrifugal fi eld and the rotor speed rpm (in min-1).

#Unit 1. Molecules and their Interaction Relevant to Biology

Antiparallel sheets are usually arranged with all their hydrophobic residues on one side of the sheet. 

This requires an alternation of hydrophilic and hydrophobic residues in the primary structure of peptides involved in antiparallel b-sheets because every other side chain projects to the same side of the sheet

In DNA polymerase, the nucleotide-binding pocket cannot accommodate a 2’-OH on the in-coming nucleotide. This space is occupied by two amino acids that make van der Waals contacts with the sugar ring. Changing these amino acids to other amino acids with
