The correct answer is Ribosomes is the single molecule that could do both cellular work and replicate itself.
Ribosomes have two primary functions: message decoding and peptide bond formation. The ribosomal subunits are made up of two large ribonucleoprotein particles (RNPs) of unequal size. Each subunit is composed of one or more ribosomal RNAs (rRNAs) and a large number of ribosomal proteins (r-proteins). The ribosome is an ancient molecular fossil that can be used to peer into the origins of life. In all living systems, the ribosome, which is composed of RNA and protein, converts mRNA to coded protein. Translation is infused with universality, economy, centrality, and antiquity. Because the ribosome is so important to all aspects of life and reproduction in an organism, rapid change is unlikely to survive. The ribosome components are an excellent resource for studying the evolution of all organisms because all cellular organism have ribosomes .
Based on a number of considerations, it is hypothesized that at some time in the evolution of life, there must have been a single molecule that could do both cellular work and replicate itself. A possible molecule that has been suggested is a catalytic RNA molecule, now called a ?
