There are some given statements about co-translational translocation in endoplasmic reticulum

a)SRP and the nascent polypeptide chain–ribosome complex bind to the integral membrane translocon

b)SRP and the nascent polypeptide chain–ribosome complex is strengthened by the binding of GTP to both the SRP and its receptor.

c)ER signal sequence emerges from the ribosome, it is bound by a signal recognition particle (SRP)

d)Hydrolysis of the bound GTP accompanies disassembly of the SRP and SRP receptor

e)Hydrolysis of the bound GTP initiates opening of the translocon, where translocation can take place

You and your lab partner have isolated 20 new mutant yeast strains that are defective in synthesis of threonine, an amino acid. These Thr- mutants do not grow on minimal medium, but they do grow on minimal medium supplemented with threonine. Ten of your Thr- mutants (numbered 1 through 10) were isolated in a strain of mating type a (MAT a). The other 10 Thr mutants (numbered 11 through 20) were isolated in a strain of mating type α (MAT α). You and your lab partner cross each of the MAT a strains to each of the MAT α strains, and you include crosses to the appropriate wild-type strains. Your experimental observations are shown in the table below, where (-) indicates diploids that did not grow on minimal medium and (+) indicates diploids that did grow on minimal medium.
