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.

WebMay 17, 2024 · A stop codon is a single nucleotide triplet that provides an end-point for protein synthesis. If you already know something about how proteins are made inside the cell (do ribosomes and transfer RNA ring a bell?), you can imagine the line of messenger RNA working its way through a ribosome. A stop codon tells the ribosome and transfer … WebOnce it does this, mRNA leaves the nucleus and goes into the cytoplasm. mRNA will then attach itself to a ribosome. The strand of mRNA is then read in order to make protein. They are read 3 bases at a time. These bases are called codons. tRNA is the fetching puppy. It brings the amino acids to the ribosome to help make the protein.

WebAt the same time a peptide bond is made between the two amino acids, and the first one (the methionine) breaks away from its transfer RNA. That transfer RNA molecule leaves the ribosome and goes off to pick up another methionine. Now the process repeats.
