Host-pathogen interactions are an ongoing arms race; pathogens evolve to express unique structures that avoid host detection, and the host germline-encoded recognition system co-evolves to match these new challenges. However, because pathogens generally have much shorter life cycles than their vertebrate hosts, and some utilize error-prone DNA polymerases to replicate their genomes, pathogens can evolve rapidly to evade host encoded recognition systems. Which error prone DNA polymerase is used  by human?

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
