I was think about buying a 1999-2005 Silver Pf69 Ultra Cameo State Quarters in either Pcgs or Ngc. I was wondering what grading service is the best out of...
There are two different locations where ribosomes can be found in a  cell. These two locations are suspended in the cytosol and attached  to the endoplasmic reticulum.
The 70 S and 80S ribosomes help in protein sythesis. 1. Ribosomes are bound to the endoplasmic reticulum, creating rough endoplasmic reticulum in eukaryotes, while in prokaryotes ribosomes are distributed in the matrix of cell. 2. Both types of ribosomes are the sites of protein synthesis. 3. They are of two types. The two types of ribosomes are 70S and 80S found in the cells of prokaryotic and eukaryotic cells, respectively. Thank.
