On the ribosome, mRNA binds ____; the peptidyl transferase
reaction occurs ____.

a) to the large subunit; on the small subunit.

b) to the small subunit; on the large subunit.

c) between the subunits; on the large subunit.

d) between the subunits; on the small subunit.

Answer Posted / madhu kumar

b)is the correct ans.The m-rna binds to the small sub unit
and forms 30s initiation complex.The poly peptidyl
transferase occurs with the large sub unit.The t-rna's
transports the amino acids to p-site and A-site in the
larger sub unit and process is completed with the aid of GTP
by the enzyme tranlocase.
