Ribosomes are a large and complex molecular machine that catalyzes the synthesis of proteins, referred to as translation. The ribosome selects aminoacylated transfer RNAs (tRNAs) based on the sequence of a protein-encoding messenger RNA (mRNA) and covalently links the amino acids into a polypeptide chain. Ribosomes from all organisms share a highly conserved cat… WebbRibosomes dissociate into large and small subunits when they are not synthesizing proteins and reassociate during the initiation of translation.

Small and large ribosomal units

WebbThe eukaryotic small ribosomal subunit(40S) is the smaller subunit of the eukaryotic 80S ribosomes, with the other major component being the large ribosomal subunit (60S). The "40S" and "60S" names originate from the convention that ribosomal particles are denoted according to their sedimentation coefficientsin Svedberg units. WebbRibosomal subunits are large nucleoprotein particles, which possess both nucleic acid (RNA) and several proteins. Generally, the molecular weight of ribosome is nearly 2.7×106 Daltons. 16S rRNA and 21 proteins together constitute the formation of the smaller subunit, i.e. 30-S subunit of the ribosome.
