Ribosome — Science definition
Defined in 3 courses:
- A machine about 20 nanometres across that builds a protein by joining amino acids in the order an instruction specifies. (Life Science & Scientific Inquiry)
- The molecular machine that reads the cell's instructions and builds proteins by linking amino acids together. (Life Science: Biology)
- The cell structure that reads mRNA and links amino acids together to build a protein. (Life Science: Biology)
Where it is taught
- Cell Structures & Organelles — Cells, Transport & Cellular Energy, Life Science & Scientific Inquiry, Grade 7
- Prokaryotic & Eukaryotic Cells & Their Organelles — Cells, Membranes & Exchange, Life Science: Biology, Grade 10
- Protein Synthesis — DNA, Inheritance & Gene Expression, Life Science: Biology, Grade 10
In use
Those instructions are read by the ribosomes, the tiny machines that string amino acids together into proteins.
Prokaryotic & Eukaryotic Cells & Their Organelles
Out in the cytoplasm, the mRNA docks with a ribosome, the molecular machine that carries out translation.
