Ribosomal subunits of eukaryotes

WebbEukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. Their large subunit is composed of a 5S RNA (120 nucleotides), a 28S RNA (4700 nucleotides), a 5.8S subunit (160 nucleotides) and ~49 proteins. The 40S subunit has a 1900 nucleotide (18S) RNA and ~33 proteins.

Webb30 sep. 2024 · In eukaryotes, the sites of ribosome formation are the cytoplasm and the nucleus. The ribosome of eukaryotes is the 80S as opposed to the ribosome of prokaryotes, which is 70S. The 80S ribosome consists of a large subunit (60S) and a small subunit (40S). Each of these subunits is composed of ribosomal protein and rRNA(s). WebbRibosomes dissociate into large and small subunits when they are not synthesizing proteins and reassociate during the initiation of translation. Prokaryotic ribosomes have a 30S small subunit and a 50S large subunit, while eukaryotic ribosomes have a 40S small subunit and a large 60S subunit.
