A ribosome is a molecular machine that links amino acids together to form messenger RNA (mRNA) cells.

Ribosomes are not an organelle (they are not membrane bound).


Ribosomes are composed of RNA and proteins, making them ribonucleicproteins.


Ribosomes have 2 subunits:

  • Smaller ones binds to the mRNA pattern
  • Larger one binds to transfer RNA (tRNA) + amino acids

After it's read the mRNA the two subunits split apart.
