Enzymes made of proteins are used to help speed up biological processes. Other proteins support cell functions and are found embedded in membranes. Proteins even make up most of your hair. When a cell needs to make proteins, it looks for ribosomes. read more
In bacterial cells, ribosomes are synthesized in the cytoplasm through the transcription of multiple ribosome gene operons. In eukaryotes, the process takes place both in the cell cytoplasm and in the nucleolus, which is a region within the cell nucleus. read more
Ribosomes are small organelles found in the cells of all life forms. They are quite small, only a few hundred nanometers across, and are composed of ribosomal ribonucleic acid (rRNA) and other catalytic proteins. read more
The ribosome is the cellular structure and location of translation, or protein synthesis. It is composed of rRNA and protein. Normally, ribosomes are in the cytoplasm as a small subunit that recognizes and binds to an mRNA transcript and a large subunit, which is recruited to the small subunit to translate the mRNA into protein. read more
