ribosome

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 - Science Notes and Projects
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
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
What Is a Ribosome? Structure, Function, and Facts
A ribosome is a tiny molecular machine inside every living cell that builds proteins It reads genetic instructions carried by messenger RNA and links amino acids together in the correct order, producing the proteins your body needs for everything from muscle contraction to immune defense
What Do Ribosomes Do? Protein Synthesis Explained
Ribosomes turn genetic instructions into proteins your body needs Learn how they work, what they’re made of, and why they matter for health
Ribosomes: from conserved origin to functional medical mobility and . . .
Ribosomes, the molecular machines that translate the genetic code from mRNA into proteins in all living cells, are highly structurally conserved across all domains of life and hence are believed to have evolved from a structurally unified pocket
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
Ribosomes: Structure, Function, and Role in Protein Synthesis
The ribosome is an astonishing example of biological efficiency It can translate a protein at a rate of 10 to 20 amino acids per second in eukaryotic cells—and even faster in bacteria
