1. 16S rRNA
A large polynucleotide (about 1500 bases) which functions as a part of the small subunit of the ribosome of prokaryote s and from whose sequence evolutionary information can be obtained; the eukaryotic counterpart is 18S rRNA.

2. Aminoglycoside antibiotics
A group of antibacterial drugs (such as kanamycin , neomycin and streptomycin ) which are mostly produced by fungi and which contain an amino sugar , and amino- or guanido-substituted inositol ring, and other sugar residues. They are all broad-spectrum antibiotic s that inhibit bacterial protein synthesis by binding to their ribosome s. However, all these drugs are toxic to humans and aren't used except in special situations.

3. Binding sites
Areas on the ribosome within which tRNA -amino acid complexes fit during protein synthesis.

4. Cycloheximide
An antibiotic derived from the bacterium Streptomyces griseus which inhibits protein synthesis in eukaryotic (nucleated) cells by blocking the traslation of messenger RNA on ribosome s.

5. Elongation factors
Certain protein s that ribosome s need to make polypeptide chains longer.

6. Endoplasmic reticulum (ER)
A network of membranous tubules in the cytoplasm of a cell; involved in the production of phospholipids , proteins , and other functions. Rough ER is studded with ribosomes ; smooth ER is not.

7. Erythromycin
An antibiotic that disrupts bacterial protein synthesis by binding to their ribosome s and inhibiting translocation .

8. Exit domain
One of the two main binding sites on the ribosome molecule. The finished portion of the polypeptide being translated is attached to this site and leaves the ribosome from this site when the entire polypeptide is finished.

9. In vitro protein synthesis
Translation of an mRNA molecule into polypeptide s within a laboratory mixture which contains ribosome s and all of the necessary components (as opposed to translation within a living cell , where protein synthesis normally occurs).

10. In vitro transcription / in vitro translation
The transcription of a DNA molecule into mRNA molecules, and the subsequent translation of the mRNA molecules into polypeptide s, within a laboratory mixture which contains ribosome s, enzyme s, and all of the necessary components (as opposed to transcription and translation within a living cell , where they normally occur).
