Question

What occurs in a ribosome in the cytoplasm?

Answer 1

Large and small units of ribosomes bind with mRNA in a process called translation

Answer 2

A ribosome is a cell organelle. ... Ribosomes are found 'free' in the cytoplasm or bound to the endoplasmic reticulum (ER) to form rough ER. In a mammalian cell there can be as many as 10 million ribosomes. Several ribosomes can be attached to the same mRNA strand, this structure is called a polysome.
                         Ribosomal protein synthesis in eukaryotes is a major metabolic activity. It occurs, like most protein synthesis, in the cytoplasm just outside the nucleus. Individual ribosomal proteins are synthesized and imported into the nucleus through nuclear pores.
