80S ribosome

The 80S ribosome is a complex molecule in eukaryotic cells (like those in humans) that acts as the cell's protein factory. It is made up of two parts: a large subunit and a small subunit, each composed of proteins and ribosomal RNA. These parts come together to read messenger RNA (mRNA) sequences and assemble amino acids into proteins, which are essential for cell function. The "80S" designation refers to its size and density, distinguishing it from smaller ribosomes in simpler organisms. Overall, the 80S ribosome is vital for translating genetic instructions into functional proteins.
