DIAGRAM: Microtubules / Rough Endoplasmic Reticulum PHOTO
Large, multi-subunit, macromolecular assemblies composed of specialized RNA and protein. The site translation of mature messenger RNA into amino acid sequences.
protein-making sites within cells
a structure found within the cytoplasm of cells, made up of protein and RNA, that serves as the site of protein synthesis.
sites where cell synthesizes new protein molecules. Some ribosomes float, others attach to the ER.
Cytoplasmic structures composed of rRNA and protein, where proteins are assembled from amino acids during translation.
numerous small particles of RNA within the cytoplasm of cells that facilitate protein synthesis.
Small cellular components composed of specialised ribosomal RNA (rRNA) and protein ; the site of protein synthesis.
Subcellular unit composed of specific rRNA molecules and a large number of proteins that are responsible for protein synthesis.
Small organelles made of rRNA and protein in the cytoplasm of prokaryotic and eukaryotic cells; aid in the production of proteins on the rough endoplasmic reticulum and ribosome complexes. The site of protein synthesis. The ribosome is composed of two subunits that attach to the mRNA at the beginning of protein synthesis and detach when the polypeptide has been translated. PICTURE
The intracellular, molecular machines that carry out protein synthesis. Associated with RNA and often attached to the endoplasmic reticulum.
Each cell contains thousands - Miniature 'protein factories' - Composes 25% of cell's mass - Stationary type: embedded in rough endoplasmic reticulum - Mobile type: injects proteins directly into cytoplasm
extremely small grain-like organelle that provides the sites for protein synthesis (they may be free in the cytoplasm or attached to the endoplasmic reticulum)

Small cellular components composed of specialized ribosomal RNA and protein; site of protein synthesis. See ribonucleic acid (RNA).
Organelles in the cytoplasm on which proteins are synthesized by the cell.
