The S is the Svedberg unit, used to express sedimentation coefficients of biomolecules and cell components. It is essentially an express of speed. The smaller the S value, the slower the molecule moves in a centrifuge.
Sedimentation coefficients are not additive. A 70S ribosome is composed of a 50S subunit and a 30S subunit.

The 40S ribosomal subunit is a component of the eukaryotic ribosome responsible for decoding mRNA and initiating protein synthesis. It plays a key role in binding tRNA molecules and facilitating the assembly of the ribosome complex during translation.

Actually, this does not stand for subunits. It stands for svedborg. This has to do with the rate of sedimentation while being centrifuged--a smaller number indicates a faster sedimentation rate.

It is the unit for sedimentation rate. Larger the value, larger the size of the particle.

What are the parts of the ribosome?
In eukariyotes there are two subunits.60s unit and 40s unit
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
what is the cell found in ribosomes?
ribosomes are not cells, they are organelles that produce and synthesize proteins. get it straight!
What organelle are proteins synthesized with?
It is the ribosome. Proteins are synthesized on that
What happens when ribosome parts pass into cytoplasm?
The ribosome subunits come together and form a functioning ribosome.

Why does 80s ribosome are written as 60s 40s ribosomes?
The nomenclature for ribosomes is based on their sedimentation rate in a centrifuge, not their molecular weight. The 80S ribosome consists of a 40S small subunit and a 60S large subunit. The small subunit (40S) rotates faster and has a lower sedimentation rate compared to the large subunit (60S).
Where must An MRNA Attach Before Protein Can Begin?
The ribosome.
What two things make up ribosomes and are are ribosomes surrounded by membrane like other organelles?
Ribosomes are not membrane bound, they are free cytoplasmic organelles responsible for the translation of cytoplasmic mRNA's. When a ribosome begins to synthesize proteins that are needed in some organelles, the ribosome making this protein can become "membrane-bound". In eukaryotic cells this happens in a region of the endoplasmic reticulum (ER) called the "rough ER". The newly produced polypeptide chains are inserted directly into the ER by the ribosome and are then transported to their destinations. Ribosome in eukaryotes are called 80S ribosomes and consist of a small 40S subunit and a larger 60S subunit. Prokaryotes have 70S ribosomes consisting of a 30S and 50S subunits. Hope this helps.
Are eukaryotic ribsomes composed of 60S and 40S subunits?
Yes, eukaryotic ribosomes are composed of a large 60S subunit and a small 40S subunit that come together to form the functional 80S ribosome. These subunits are made up of both RNA and protein components, with the 60S subunit containing 3 types of rRNA molecules and over 49 proteins, while the 40S subunit contains 1 type of rRNA and around 33 proteins.
what is the cell found in ribosomes?
ribosomes are not cells, they are organelles that produce and synthesize proteins. get it straight!
What are the chemical components of ribosomes are proteins?
Ribosomes are primarily composed of RNA and proteins. The RNA component is responsible for the catalytic activity of ribosomes in protein synthesis, while the proteins provide structural support and aid in the overall function of the ribosome.
What organelle are proteins synthesized with?
It is the ribosome. Proteins are synthesized on that
