70S refers to the rate of sedimentation of the ribosome in a centrifuge. You can almost think of it as a unit of size. The "S" is a unit of measurement called the Svedberg unit. Ribosomes contain two subunits. In prokaryotes, these subunits are 50S (large) and 30S (small). The total ribosome with both subunits is 70S in prokaryotes. (Notice that 30 + 50 = 80 and not 70. Remember this is not size and the rate of sedimentation is less when the subunits are bound then when they are separated.) Eukaryotic cells have 80S ribosomes: 60S (large) and 40S (small) subunits.

Are ribosomes in the planet or animal cell?
Ribosomes can be seen in every living cell.70s ribosomes in prokaryotes and 70s and 80s in eukaryotes.
Which organelle produces proteins in both eukaryotes and prokaryotes?
The ribosomes are the small organelles responsible for protein synthesis. They are found in both eukaryotic and prokaryotic cells, but are smaller in prokaryotic cells (70s vs 80s).
Prokaryotes have what structure necessary for protein synthesis?
Prokaryotes have ribosomes that are necessary for protein synthesis. The ribosomes found in eukaryotes are larger compared to those found in prokaryotes.
Why ribosomes are attached to DNA in prokaryotes?
=== === ---- === === === === ---- === ===
Are ribosomes found in prokaryotic cells?
Ribosomes are small organelles that can be found inside a prokaryotic cell.
Is ribosomes a prokaryotes?
70s ribosomes are in prokaryotes.80s ribosomes are found only in eukaryotes.
Prokaryotes have ribosomes?
Yes they have ribosomes.They have 70s ribosomes
What are 70s ribosomes?
They are found in prokaryotes. Eukaryotes have 80s ribosomes
Is ribosomes prokaryote?
70s ribosomes are in prokaryotes.80s ribosomes are found only in eukaryotes.
Are ribosomes in the planet or animal cell?
Ribosomes can be seen in every living cell.70s ribosomes in prokaryotes and 70s and 80s in eukaryotes.
Does prokaryote have ribosomes?
Yes, prokaryotes have ribosomes.They have 70s ribosmes.They are smaller than eukariyotic 80s ribosomes
Do prokaryotes contain ribosomes?
Not gurranteed BUT prokaryotic cells are almost as big as a eukaryotic cells, so i think eukaryotic!Prokariyotes have 70s ribosomes.Eukariyotic cells got 80s ribosmes. This is a measure of size
Why ribosomes are of 70s in mitochondria of eukaryotic cell?
Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit.
What are the differences between prokaryotic ribosomes and eukaryotic ribosomes?
Prokaryotic ribosomes are single celled ribosomes and eukryotic ribosomes are multi cellular ribosomes
What is two types of ribosomes and mitochondria?
The difference between ribosomes of prokaryotes and eukaryotes is the structure of the ribosomes. Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit. In eukaryotes, the ribosomes may be classified as either 'free' or 'bound'. Free ribosomes may be found suspended in the cytosol whereas bound ribosomes are attached to endoplasmic reticulum (as such called rough endoplasmic reticulum).
What is 70s ribosomes?

Does E coli cells have ribosomes?
yes.They have 70s ribosomes.All prokariyotes have 70s ribosomes
