Detailed explanation-1: -Translation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain. Illustration of the molecules involved in protein translation. A ribosome is shown with mRNA and tRNA.
Detailed explanation-2: -A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.
Detailed explanation-3: -Characteristics. Translation initiation involves (1) the dissociation of the ribosome into small and large subunits (SSU and LSU; 30S and 50S in bacteria and archaea and 40S and 60S in eukaryotes), (2) the binding of mRNA and Met-tRNA Meti to the SSU to form SSU IC, and (3) the joining of the LSU, with the SSU IC (Fig.
