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"

Example sentences
The ribosomes in turn interpret the DNA string to make proteins.
There are genes that code the proteins that make up the ribosome for example.
Once the tRNA has a weird aminoacid, the ribosome blindly use it in the proteins.
Interesting parallel with DNA here, the ribosome as the robot and the blocks as the RNA strands.
The ribosome only connect the aminoacid that are selected by the t-RNA.
But then the result of the computation is dependent on hundreds of factors outside of both the DNA and the ribosome.
It's quite amazing that we manufacture transistors that are as small as a ribosome assembly
If you think of DNA as code, genes as specific programs, you can think of expression as how often those programs are run. "Running" in this sense means that the gene is copied to messenger RNA and send to the ribosome to synthesize proteins.
My colleague was just scooped in Science on work that disproves the ribosome spacing hypothesis when it comes to translation initiation and codon optimization.
The ribosome is an excellent example: it's a huge protein/RNA complex, which is also an enzyme responsible for enabling the second part of the central dogma.
This is very similar to earlier discoveries that the choice of codon can be intimately tied in with protein domains folding; allowing proteins to partially fold while the remainder is "stalled" on the ribosome waiting for the rare codon.
"I mean, you really can't think up a good use for enough computing power to compute a Mersenne prime every few seconds?Let me give it a shot:Discretize a space about the size of a big protein plus a ribosome plus a few hundred nucleotides.
We used a combination of representing copy numbers of molecular species and representing individual molecules of a few specific types: DNA polymerase, RNA polymerase, ribosome, FtsZ
> Maybe one day we'll find a virus-type replicator that also contains ribosomes - and what then?Mimivirus, another giant virus, has its own gene for an amino-acyl t-RNA synthase, an enzyme that loads an amino acid onto a transfer RNA to be used in making proteins.
