Retrotransposons could provide that variation, by affecting gene expression at random, depending on where they pitch up.
ECONOMIST: Brain development may be influenced by genetic parasites
Gene expression is complicated, and a good portion of it is very much dependent on environmental factors.
During the first of these, I worked on various aspects of gene expression and regulation in viruses and mammalian cells.
In order to ensure that this gene expression is properly regulated, the researchers also introduced a different molecule into the yeast.
FORBES: Cyborg Yeast Have Their Genes Controlled By Computer
San Francisco and ETH Zurich have developed a method that enables them to precisely control gene expression in individual cells of yeast.
FORBES: Cyborg Yeast Have Their Genes Controlled By Computer
Finally, the team investigated the mechanisms behind these differences in gene expression.
This combination of technique allows for precise control of gene expression in yeast, which is something that can be useful for genetic engineering.

Thinking of contingency plans rather than blueprints, in my opinion, makes it easier to add the influence of environment into the understanding of gene expression.
Prenatal insults including chemical and radiation exposure can create epigenetic patterns of gene expression that will stay with you forever, even if your actual genes are undamaged.
FORBES: 1st Person | Facing an Unsettled Future After Radiation Exposure
He has spent the last ten years trying to build them and has come up with of 70, 000 DNA parts that can be used to control gene expression.
Again, like the problems with figuring out the genes and gene expression, the simple aspect of gestation will also likely produce uplifted, intelligent animals that may be deformed and doomed to suffer.
To get a new gene count, Velculescu and his colleagues used a different technology called serial analysis of gene expression (SAGE), which was developed at Johns Hopkins University and licensed to Cambridge, Mass.
Merck (nyse: MRK - news - people ), the world's third-largest drug company, is using gene expression arrays, also known as DNA chips, to keep clinical duds from reaching expensive animal or human trials.
Rudolf Jaenisch. (Applause.) The 2010 National Medal of Science to Rudolph Jaenisch, Whitehead Institute for Biomedical Research and Massachusetts Institute of Technology, for improving our understanding of epigenetic regulation of gene expression, the biological mechanisms that affect how genetic information is variably expressed.

Here, it acts on gene-expression and disrupts brain activity, brain development or both.
The Rosetta purchase gave Merck expertise in figuring out exactly which genes the body is reading--a technology called gene-expression profiling.
For example, if a yeast cell was genetically modified to include a particular gene, this technique would allow the expression of that gene to come under precise control.
FORBES: Cyborg Yeast Have Their Genes Controlled By Computer
Then we looked for any spikes, any differences, in the expression pattern from one gene to another.
Eugenol, like other antidepressants, increases expression of brain-derived neurotrophic factor (BDNF) gene in the hippocampus, which is necessary for an antidepressant to exhibit its activity.
