Title: Assistance Needed-Differentiation of Ribosomes Post by: Dannyy on Feb 25, 2015 The question I was asked was if the ribosomes in eukaryotic cells and prokaryotic cells have the same molecular structure. I know that they perform the same function but do they have the same molecular structure?

Title: Re: Assistance Needed-Differentiation of Ribosomes Post by: 2444256703 on Mar 11, 2015 Both cell types have many, many ribosomes, but the ribosomes of the eukaryotic cells are larger and more complex than those of the prokaryotic cell. Ribosomes are made out of a special class of RNA molecules (ribosomal RNA, or rRNA) and a specific collection of different proteins. A eukaryotic ribosome is composed of five kinds of rRNA and about eighty kinds of proteins, while prokaryotic ribosomes are composed of only three kinds of rRNA and about fifty kinds of protein.
