Because repression of a jumping gene
also affects genes located near it on the chromosome, the researchers suspect that these repressors have been co-opted for other gene-regulatory functions, and that those other functions have persisted and evolved long after the jumping genes
the repressors originally turned off have degraded due to the accumulation of random mutations.
Among the topics are the performance comparison of jumping gene
adaptations of an elitist non-dominated sorting genetic algorithm, a robust multi-objective genetic algorithm with online approximation under interval uncertainty, chance constrained programming to handle uncertainty in nonlinear process models, the ecodesign of chemical processes with multi-objective genetic algorithms, and the multi-objective optimization of a hybrid steam stripper-membrane process for the continuous purification of bioethanol.
Geneticist Virginia Walbot at Stanford University has discovered a special kind of jumping gene
called a "mutator transposon," endemic in a Mexican maize called Zapalote chico and grown only by Zapotec farmers near the town of Tehuantepec in Oaxaca.
Multiobjective optimization methodology; a jumping gene
So if two species share a jumping gene
, they probably inherited it from a common ancestor.
An initial event, whereby the Accord jumping gene
jumped in front of Cyp6g1 in a single fruitfly--which possibly predated the use of DDT--has spread globally to all strains of Drosophila melanogaster.
These findings take us closer, for example, to more precisely predicting the changes a drought-resistant jumping gene
from one plant put into another may cause to the DNA.
This color change also involved a third gene, which apparently activated the jumping gene
Washington, Nov 7 (ANI): Scientists have unlocked a list of genes involved in colorectal cancer, thanks to a jumping gene
with the fairy tale name "Sleeping Beauty".
The gene originates from a so-called jumping gene
that integrated in the genome of a primitive mammal at least 150 million years ago and has since then evolved an essential function.
Objective: The present structure of the human genome is largely a result of the activity of Transposable Elements (TEs) or jumping genes
The viroidal complementary DNA can function as jumping genes
producing a dynamic genome important in storage of synaptic information, HLA gene expression and developmental gene expression.
