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 are located inside the cytosol found in the plant cell and animal cells. The ribosome structure includes the following: It is located in two areas of cytoplasm. Scattered in the cytoplasm. Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes. Around 62% of ribosomes are comprised of RNA, while the rest is proteins.
Webb26 apr. 2024 · Bacteria and archaebacteria have smaller ribosomes, termed 70S ribosomes, which are composed of a small 30S subunit and large 50S subunit. The ribosomes in our cells, and in other animals, plants and fungi, are larger, termed 80S ribosomes, composed of a 40S small subunit and a 60S large subunit.

WebbThe 70S and 80S are the prokaryotic and eukaryotic ribosomes respectively. In which 70S is the combination of 30S + 50S subunit and 80S is the combination of 40S+60S subunit of the ribosome. Why do 60S and 40S make 80S not 100s? The eukaryotic ribosome contains 60S and 40S subunits and in combination makes 80S subunits of the ribosome.
