Explanation / Answer

Ans 8 : For the attachment of the translational complexes to the ER membrane , the ER signal sequence must be recognised by soluble signal recognition particles.

These signal recognition particles or SRP recognise the signal sequences that has approximately 20 amino acids consisting of hydrophobic residues.
