The process of making Ribosome. 70S !! link for Eukaryotic Ribosome (2).. 70S ribosomes are the protein synthesizing complex of many proteins and three ribosomal RNAs found in prokaryotes, ie. bacteria. S refers to the Sedimentation co-efficient (Svedberg unit). In eukaryotes, the similar complexes have 80S sedimentation.. What is 70s ribosomes? 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
A ribosome is a complex cellular mechanism used to translate genetic code into chains of amino acids. Long chains of amino acids fold and function as proteins in cells Biochemistry Ribosome Molecular Biology. Why do 60S & 40S subunits make an 80S (not 100S) ribosome and, similarly, 50S & 30S make 70S
The same way an eukaryotic ribosome has a large sub-unit that sediments at 60s, a small one that sediments at 40s The researchers concluded that the 32S and 51S peaks were components of the 70S peak and that the 100S peak was a dimer of two 70S particles Structure of Ribosome Modulation Factor bound to 70S Ribosome.

A ribosome is the organelle upon which mRNA from DNA transcription is translated to a polypeptide with a specific amino acid sequence defined by the genetic code. The size of the ribosome in eukaryotes and prokaryotes are slightly different Ribosomes consist of two major components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain. The ribosomes and associated molecules are also known as the translational apparatus
