WordNet (r) 3.0 (2006) (WordNet)

ribosome
n 1: 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 use by the cell; "the ribosome is the
site of protein synthesis"

核糖体（Ribosome），旧称“核糖核蛋白体”或“核蛋白体”，普遍被认为是细胞中的一种细胞器，除哺乳动物成熟的红细胞，植物筛管细胞外，细胞中都有核糖体存在。
Ribosome | Definition, Function, Formation, Role, Importance, Facts . . .
Ribosome, particle that is present in large numbers in all living cells and serves as the site of protein synthesis Ribosomes occur both as free particles in prokaryotic and eukaryotic cells and as particles attached to the membranes of the endoplasmic reticulum in eukaryotic cells
Ribosomes Function, Structure, and Facts - Science Notes and Projects
The ribosome’s active site, located in the large subunit, catalyzes the formation of peptide bonds between amino acids, extending the growing polypeptide chain
The ribosome comes to life: Cell
The ribosome is an ancient molecular machine that coverts the genetic information carried by mRNA into protein, a crucial step in linking genotype to phenotype
Ribosome - National Human Genome Research Institute
Ribosome A ribosome is the cellular machinery responsible for making proteins There are many ribosomes in each cell, each made up of two subunits These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon
Ribosomes: from conserved origin to functional medical mobility and . . .

The ribosome catalyzes the assembly of amino acids into peptide chains of defined sequence, as dictated by the interaction of amino-acid-carrying transport RNAs (tRNAs) with complementary
Ribosomes | Anatomy and Physiology | Research Starters - EBSCO
Ribosomes are essential cellular structures responsible for synthesizing proteins through a process known as translation They interpret the genetic information carried by messenger ribonucleic acids (mRNAs) to assemble amino acids into polypeptides While ribosome structure is generally consistent across all cells, significant size differences exist between prokaryotic ribosomes, which are
Ribosomes: Structure, Types, Functions and Diagram
The ribosome is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation) Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules
