WebRibosome binds to the mRNA near the 5’ capped end and translation starts at the Kozak sequence: 5’-GCC(G or A)CCAUGG-3’ Met-tRNA is bound to an initiation factor and to small ribosomal subunit When it finds the first AUG: large rRNA subunit binds and translation begins. Ribosomes are protein-synthesising machines WebRibosomal 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.
