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.

How is ribosomes like a zoo?
Ribosomes produce proteins. In a zoo, ribosomes would most likely be a food vendor.
Protein factories of the cell?
Ribosomes
What does ribosome make?
Ribosomes synthesize protein.
Why do dogs have ribosomes?
Ribosomes are essential cellular organelles found in all living organisms, including dogs. They play a crucial role in protein synthesis, a fundamental process for cell growth and maintenance. Thus, dogs have ribosomes to help produce the proteins necessary for their bodily functions.
What do rabosomes do?
Ribosomes are cell organelles that are responsible for protein synthesis. They read the messenger RNA and use it as a template to link together amino acids in the correct order to form a protein. Ribosomes can be found in the cytoplasm of the cell or attached to the endoplasmic reticulum.
Does E coli cells have ribosomes?

Is the ribosomes a eukaryotic?

Do prokayotes have ribosomes?
Of course they have ribosomes.They have 70s ribosomes in them.
What are 70s ribosomes?
They are found in prokaryotes. Eukaryotes have 80s ribosomes
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 smaller (70S) compared to eukaryotic ribosomes (80S). Prokaryotic ribosomes consist of a 30S and a 50S subunit, while eukaryotic ribosomes consist of a 40S and a 60S subunit. Prokaryotic ribosomes have fewer proteins compared to eukaryotic ribosomes.
Is ribosomes a prokaryotes?
