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. WebA ribosome is made up of two basic pieces: a large and a small subunit. During translation, the two subunits come together around a mRNA molecule, forming a complete ribosome. The ribosome moves forward on …
