How would you make transcription and translation work when you no longer have a nucleus? Bacteria have an interesting answer. Attenuation, or dampening, of the trp operon is made possible by the fact ...

The answer lies in differential gene expression – the combination of genes that are turned on (expressed) or turned off (repressed) in particular cells – this is what makes each cell unique. Gene ...

In bacteria, transcription and translation are coupled in time and space. Two studies now show that transcription and translation are physically linked, which may be important for regulating bacterial ...

Once transcription stops, the enzyme and the mRNA transcript disengage from the template DNA, which re-winds to form a double helix. The mRNA transcript or pre-mRNA is then released for ...

Researchers synthesize recombinant proteins in cell-free extracts to verify the identity of cloned genes, to study protein-protein, protein-nucleic acid, and protein-drug interactions, and to carry ...

Whenever they don't have quality reassurance assessments and also proofreaders that happen to be highly skilled, superior plus accuracy may easily turn into a big problem. Make sure they have some ...

The delivery of municipal services is a daunting task. Demands for service are increasing. Municipalities are also subject to a variety of state and federal mandates. These often require cities to ...

Believe it or not, all of the cells within a multicellular organism (excluding red blood cells and gametes) contain exactly the same DNA. In which case, why is a heart composed of cardiomyocytes? Or ...
