Assuming this mutant strain harboured at least one particularly productive mutation, propagation of these alleles to strain R57 may be a likely outcome.
p53 transcription has been previously associated with oxidative stress-induced genotoxicity, and mediates several cellular stress responses including arrest in the cell cycle, preventing mutation propagation, initiation of DNA repair mechanisms and initiation of apoptosis when DNA damage is extensive [ 47, 50, 51].
A proper modeling of the SOS response is an essential component of developing a quantitative theory of mutation-propagation in cellular organisms, which is important for understanding phenomena such as the emergence of antibiotic drug resistance in bacteria, and cancer in multicellular organisms [2] [4].
Because the SOS response is a genetic repair pathway that works in conjuction with other cellular repair pathways, a proper understanding of the SOS response is important for developing a coherent theory of mutation-propagation that will be useful for understanding the emergence of antibiotic drug resistance in bacteria, and cancer in multicellular organisms [2] [4].
Each nd_experiment has a type (common types are phenotyping, genotyping, field collections, crossing, mutation and propagation), and a location.
In the TR7 revertants, the Trp-induced dysfunction was overcome by further mutations, and propagation on Trp was once again allowed.
In addition, no personal genome has been so extensively analyzed using DNA derived from peripheral blood as opposed to DNA from transformed cell lines that may either accumulate mutations during propagation or clonally expand mosaic variants during cell transformation and propagation.
All vectors containing the ccdB gene were propagated in the E. coli strain DB3.1, which contains the gyrA462 mutation that enables propagation of Gateway vectors encoding the ccdB gene [35].
E. coli DB3.1 contains the gyrA462 mutation that enables propagation of Gateway vectors encoding the ccdB gene [ 21]. A. tumefaciens GV3101 pMP900 [ 43] was used to assess the functionality of plant transformation vectors.
To shed light on the experimental conversion of a rigidly invariant code to a mutating code, the present study examined code mutations determining the propagation of Bacillus subtilis on Trp and 4-, 5- and 6-fluoro-tryptophans.
However, due to the privatization and increased intellectual property rights (IPRs) protection, many people in the developing world find it very difficult to access modern biotechnology research tools (e.g. genetic engineering, micro-propagation, mutation breeding etc).
