Ribosomes work like machines to translate the code sequence of mRNA into a protein.
It reads the sequence of the messenger RNA (mRNA) & using the genetic code, translates the sequence of RNA into a sequence of amino acids (called Translation).
Ribosomes can translate at a rate of 200 amino acids per minute. Ribosomes translate mRNA into polypeptide chains, which fold & assemble into proteins.
The mRNA molecule is like genetic codes written on a long thread of paper. The ribosome finds the right end of the mRNA thread & starts to read the codes. The ribosome uses the code sequence for determining the correct order of amino acids to generate the corresponding protein.
Ribosomes are found on the rough ER or free-floating in the cytosol.
