1.	In mammalian cells, the signal recognition particle (SRP) consists of ____ distinct polypeptides and one small RNA molecule.(a) 2(b) 4(c) 6(d) 8I had been asked this question in class test.I would like to ask this question from Cytoplasmic Membrane Systems in section Cytoplasmic Membrane Systems of Cell Biology
Answer» Correct answer is (c) 6 Easiest EXPLANATION: The hydrophobic SIGNAL present in the nascent polypeptide is recognized by the SRP which then BINDS to the SRP receptor and transports the PEPTIDE to the endoplasmic reticulum MEMBRANE. The signal recognition particle (SRP) consists of 6 distinct polypeptides and one small 7S RNA.
