In 80S eukaryotic ribosome, there are two subunits. One large subunit, that is, 60S and one small subunit, that is, 40S.
In animals, 60S subunit is further divided into 28- 29S + 5S + 5.8S and 40S is divided into 18S.
In plants, 60S subunit is divided into 25S +5S +5.8S and 40S subunit is divided into 16- 18S.
During translation initiation in prokaryotes, a GTP molecule is needed in
association of 30S, mRNA with formyl-met-tRNA
association of 50S subunit of ribosome with initiation complex
formation of formyl-met-tRNA
binding of 30S subunit of ribosome with mRNA
