less likely to reproduce successfully), Dworkin said. There definitely are costs to variation. In addition, this study provides preliminary evidence that a well known plant development gene ERECTA may be in part responsible for some of the change in ...
Unravelling new complexity in the genome

not aware that their favorite genes are regulated at the level of splicing. Blencowe believes that the data his group has generated provides a valuable basis for understanding molecular mechanisms by which genes can function differently in different ...

Gene regulation, not just genes, is what sets humans apart

99 percent the same genetically, they had offered the suggestion that greater differences might be found in the regulatory regions. The type of analysis performed by the Duke team couldnt be done until the macaque genome was published in 2005 becau...
