Ribosome

Ribosomes are membrane-less, circular, microcellular organelles made up of proteins and RNA, which are found in cytoplasmic mitochondria nuclei and cytoplasm on a rough endocrine vessel in a eukaryotic cell.
The ribosome was discovered by Robinson and Brown in the root of the beans.
And the Paladay salt scientist saw the ribosome in the animal cell.
There are types of ribosomes.

1.  70s  Ribosome –
                                          
It is made up of two sub-units of the 50s and 30s. The 70s type of ribosome is found in prokaryotic cells and eukaryotic cells and is also small.
2.  80s Ribosome –
                                           
It is made up of two sub-units of the 60s and 40s. 80s types of eukaryotic cells and rough endoplasmic reticulum are found in and are also large.

The ribosome is made up of two large circular structures, with the first structure being large domed and the second oval small, and the two interconnected with magnesium ions. The ribosome acts as a carrier during protein synthesis called polysome.
The ribosome mainly acts on protein synthesis. in the Ribosome “S” means svedberg unit
