What are ribosomes and where can they be found?

Ribosomes are created inside the nucleolus, which is inside the nucleus, in an animal cell. They frequently move through the endoplasmic reticulum, attaching to its walls, to get to their destinations. They are often found in the Golgi apparatus and floating freely in the cell's cytoplasm as well. read more

In Eucaryotic cells, the ribosomes are free in the cytosol until they start translating a protein, in which case the ribosome can be directed to the endoplasmic reticulum (ER) if the newly synthesized protein has the ER signal sequence. read more

Translation of messenger RNA (mRNA) by ribosomes occurs in the cytoplasm. In bacterial cells, ribosomes are scattered throughout the cytoplasm. In eukaryotic cells, they can be found both as free ribosomes and as bound ribosomes, their location depending on the function of the cell. read more
