MeSH definition : The small ribonucleoprotein component of RIBOSOMES. It contains the MESSENGER RNA
binding site and two TRANSFER RNA binding sites - one for the incoming AMINO ACYL
TRNA (A site) and the other (P site) for the peptidyl tRNA carrying the elongating
peptide chain.;
MeSH synonym : ribosome subunit, small; small ribosomal subunit; small ribosome subunit; small ribosome subunits; subunit, small ribosomal; subunit, small ribosome; subunits, small ribosomal; subunits, small ribosome; ribosomal subunits, small; ribosomal subunit, small; small ribosomal subunits;
