New Genetic Methods to suppress the effects of Down Syndrome American scientists have managed to suppress the effects of Down Syndrome in a living cell with a gene switch. The development is a major step forward in the treatment of Down. Every year dozens of children bo...
How does transcription initiate in E.Coli and other prokaryotic organisms? Transcription is a part of the central dogma of biology and describes the copying of a gene from the DNA to a messenger RNA (mRNA) which will then be translated to the protein. The copying process is very well ...
How can bacteria sense each other: bio luminescence. Vibrio fisheri are a marine gram negative bacterium and they live symbiotically with marine animals like the squid below. However these glowing bacteria are only found bio illuminating in a large enough colony....
unique heavy or light chain variable regions produced by rearrangement In immunology a major topic of discussion early on is the rearrangement of variable gene segments to form the complete variable region, either the heavy or light chains. Remember from general biology that an an...
What is a restriction enzyme This image is a cartoon rendition of the EcoRI restriction enzyme. Two catalytic magnesium ions are shown as magenta spheres and are adjacent to the cleaved sites in the DNA made by the enzyme (depicted as gap...
