  To initiate translation, the mRNA first binds to (a) the smaller ribosomal sub-unit                            (b) the larger ribosomal sub-unit (c) the whole ribosome                                                 (d) No such specificity exists

Answer:

                  (a) The ribosome consists of structural RNAs and about 80 different proteins, in its inactive state, it exist as two subunits, a large subunit and a small subunit. When the smaller subunit encounters the mRNA, the process of translation of the mRNA to protein begins.
