Detailed explanation-1: -As mentioned above, ribosomes are the molecular machines responsible for protein synthesis. A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits.

Detailed explanation-2: -Ribosomes. Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.

Detailed explanation-3: -While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol. Ribosomes are found in many places around a eukaryotic cell.

Detailed explanation-4: -The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. The nucleolus is also where ribosomal RNA genes are transcribed.

Detailed explanation-5: -Ribosomes are organelles composed of both RNA and proteins that carry out the process of protein synthesis. Ribosomes either float freely in the cytoplasm or attach to the endoplasmic reticulum; the location of a ribosome determines how the protein it synthesizes will be used.
