catalytic properties.Ribosomes have two main functions — decoding the message and the formation of peptide bonds.These two activities reside in two large ribonucle-oprotein particles (RNPs) of unequal size,the ribosomal subunits.Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-pro-teins).The small subunit (30S in bacteria and archaea, 40S in
Cell Structure All the living organisms that exist in this universe – like mushrooms, plants, humans, elephants etc. are all composed up of a basic unit called the cell. The cell is the structural and functional component of life.
detailed chemistry of ribosome function, and the backbone of the ribosome structure, whether protein or rRNA, remained unknown. A number of questions about the ribosome were answered only when the atomic resolution structure of the ribosome was determined by X-ray crystallography. 4. High resolution X-ray structure of the ribosome The pioneering work in ribosome crystallization was carried out
A ribosome is made of two parts, or subunits that lock together to carry out its function. The larger of the two subunits is about twice the size of the smaller subunit.
After solving the structures of the individual small and large subunits, the next step in ribosome structure research was to determine the structure of the whole ribosome. This work is the culmination of decades of research, which started with blurry pictures of the ribosome from electron microscopy

The structure and function of ribosomes have been studied extensively over the course of the last half-century, culminating in the recent publication of crystal structures of the prokaryotic 50S and 30S ribosomal subunits and the intact 70S ribosome. These crystallographic results revealed unequivocally that the ribosome is a ribozyme, confirming a starring role for ribosomal RNA as the
