Site of protein synthesis in the cytoplasm. selection and breeding Manipulating microbes, plants or animals, and choosing desirable individuals or populations as breeding stock for new generations.
A subcellular particle composed of RNA and protein, which is part of the protein-synthesising machinery of the cell.
A heterodimeric multi-subunit enzyme composed of ribonucleoprotein and protein subunits. Interacts with aminoacylated tRNAs, and mRNAs and translates protein coding sequences from messenger RNA. During protein elongation, the nascent protein is held at the P-site (peptidyl-tRNA complex), while aminoacyl-tRNAs bearing new aminoacids are bound at the A-site. Similar ribosomes are found in all living organisms, all composed of large and small subunits, as well as chloroplasts and mitochondria. Differences are apparent between prokaryotic and eukaryotic ribosomes.
The ribosome is a large and complex molecular machine, found within all living cells, that serves as the primary site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules. Ribosomes consist of two major components — the small ribosomal subunit which reads the ...Found on http://en.wikipedia.org/wiki/Ribosome
<cell biology> A small particulate organelle found in prokaryotes and eukaryotes and also within mitochondria and chloroplasts, but differing in size and composition. Made of two subunits, each being an RNA protein complex. Ribosomes are responsible for the translation of mRNA which may occur in the cytoplasm (see polyribosomes) or on rough e...Found on http://www.encyclo.co.uk/local/20973

(ri´bo-sōm) any of the intracellular ribonucleoproteinorganelles concerned with protein synthesis, found either bound to cell membranes or free in the cytoplasm. They may occur singly or in clusters (polyribosomes). The genetic code is translated when ribosomes attach to messenger RNA.Found on http://www.encyclo.co.uk/local/21001
an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for u...Found on https://www.encyclo.co.uk/local/20974

Protein-making machinery of the cell. Active ribosomes are either located on the endoplasmic reticulum (ER) of eukaryotic cells or dissolved in the cytoplasm (of any kind of cell), and are made of proteins and a special type of RNA, ribosomal RNA.

This is a small granular organelle, of which several thousand may be present in a given cell, congregating especially on the membranous walls of the endoplasmic reticulum. It is the place where single molecules of protein can be synthesised.
