Because ribosomes are so important to cells, changes in RNA sequences could prove a disaster.What biologists call a species is becoming more than just a name | Jack J. Lee | October 14, 2021 | Science News For Students
These mRNAs would pass these instructions onto the ribosomes, the cellular protein and peptide-making machines, which would assemble them accordingly.The Rise of RNA Therapeutics - Issue 107: The Edge | Lina Zeldovich | September 29, 2021 | Nautilus
Once inside the cells, the “protein-making factories,” or ribosomes, use these instructions to build copies of the spike protein.If you’re unsure about getting the COVID-19 vaccine, read this | Kate Baggaley | September 28, 2021 | Popular-Science

Scientific definitions for ribosome
A sphere-shaped structure within the cytoplasm of a cell that is composed of RNA and protein and is the site of protein synthesis. Ribosomes are free in the cytoplasm and often attached to the membrane of the endoplasmic reticulum. Ribosomes exist in both eukaryotic and prokaryotic cells. Plastids and mitochondria in eukaryotic cells have smaller ribosomes similar to those of prokaryotes. See more at cell.
