what is eukaryotic ribosomal associate? and how is it computed ?

Solution

Eukaryotic cytoplasmic ribosome associate includes 80s which have larger and smaller subunit fraction bound together by Mg2+ ions.

60s larger unit is made up of 28s rRNA,5.8s rRNA ,5s rRNA and 46 proteins. Like this 40s subunit is made up of 18s rRNA and 33 proteins.

Eukaryotic chloroplast and mitochondrial ribosomes are 70 s type which have 30 and 50s fractions. 30s have 16s r RNA and 21 proteins , larger subunit 50s is made up of 5s rRNA,23 srRNA and 31 Protein.
