Ribosomes amazing nano machines

Translation is one of the most complex biological processes, involving diverse protein factors and enzymes as well as messenger and transfer RNAs. The sequence of the PTC is possibly the most relevant stretch of nucleic acid to be studied if one aims to understand the origin of life. Nowadays, it is a consensus that the ribosome should be understood as a prebiotic machine that predated the origin of cells. The contingent appearance of this ribozyme capable of binding amino acids together was crucial to both the initial emergence and further development of the phenomenon of life7
The ribosome is a ‘‘living fossil‘‘, a particle so central to all cellular processes that it has essentially become frozen in time, preserving many ancestral features in its molecular structure. 8
The origin of the ribosomal protein synthesis network is considered to be the singular defining event in the origin of cells and the Tree of Life 4
