WebA ribosome receives the mRNA molecule and starts to build a chain of amino acids (a protein) that exactly matches the instructions within the mRNA. The ribosome ‘reads’ the mRNA sequence as a series of three- base chunks or codons. Each codon tells the protein-making machinery which amino acid to add next. WebJun 27, 2005 · We know that tRNAs bind to ribosomes by spanning the interface between the ribosomal subunits, with the aminoacyl end binding to the 50S ribosomal subunit and the anticodon loop binding to an mRNA codon within the 30S ribosomal subunit. ...
