ribosome

n. 核糖体

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"

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
Ribosomes are macromolecular machines found in all living cells that synthesize proteins by translating messenger RNA (mRNA) Located in the cytoplasm, ribosomes either float freely or attach to the endoplasmic reticulum in eukaryotic cells
Ribosomes: Definition, Structure, Functions, with Diagram
Ribosomes are cell structures present in large numbers in all living cells acting as the site of protein synthesis In prokaryotes, they float freely in the cytoplasm, while in eukaryotes they are free or remain bound to the outer membrane of the endoplasmic reticulum They are also found in the mitochondria and chloroplast of a eukaryotic cell
Ribosome - National Human Genome Research Institute
A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins
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
ribosome | Learn Science at Scitable - Nature
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells In 1955, George E Palade discovered ribosomes and described
Ribosome | British Society for Cell Biology - BSCB
Ribosomes are macro-molecular production units They are composed of ribosomal proteins (riboproteins) and ribonucleic acids (ribonucleoproteins) The word ribosome is made from taking ‘ ribo ’ from ribonucleic acid and adding it to ‘ soma ’, the Latin word for body Ribosomes can be bound by a membrane (s) but they are not membranous
The Ribosome - UCSC
Ribosomes are ancient molecular machines that are responsible for production of protein in all living cells They are large (2 5 MD molecular weight or larger) macromolecular complexes composed of RNA (2 3) and protein (1 3) Ribosomes read the nucleotide sequence of a messenger RNA (mRNA) into a protein sequence, using the genetic code
