Sometimes, ribosomes are visible as clusters, called polyribosomes. In eukaryotes (but not in prokaryotes), some of the ribosomes are attached to internal membranes, where they synthesize the ...

Comparing protein synthesis in prokaryotic vs ... and simpler compared to eukaryotic ribosomes. These 70S ribosomes consist of two subunits: a 30S small subunit and a 50S large subunit.

Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...
