what does it work?
is a large and complex molecular machine, found within all living cells
consist of two subunits that fit together and work as one to
translate the mRNA into a polypeptide chain during protein synthesis.
translate the mRNA into a polypeptide chain during protein synthesis.
Because they are formed from two subunits of non-equal size, they are slightly
longer in the axis than in diameter

why is it important?
Free and membrane-bound ribosomes differ only in their spatial distribution;
they are identical in structure
they are identical in structure
Free ribosomes can move about anywhere in the cytosol, but are excluded from the cell nucleus and other organelles.
Proteins that are formed from free ribosomes are released into the cytosol and
used within the cell.
