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.
