Webb28 mars 2024 · Complex chromosomal alterations are a hallmark of advanced cancers but rarely seen in normal tissue. The progression of precancerous lesions to malignancy is often accompanied by increasing complexity of chromosomal alterations that can drive their transformation through focal oncogenic amplifications. However, the etiology and … Webb5 nov. 2004 · Our study ( 1) argued that the long-term genetic effective size of a population ( Ne) plays a central role in dictating the types of genomic evolution that can occur and that many aspects of eukaryotic genome complexity may have arisen owing to a reduction in Ne that began near the time of origin of eukaryotes and became much more pronounced …

Webb7 jan. 2013 · Introduction. Why do some genomes contain a large number of noncoding nucleotides while others do not? One explanation might be that increases in noncoding DNA “emerged passively in response to the long-term population size reductions that accompanied increases in organism size” (Lynch and Conery 2003).Support for this … WebbGenomic complexity is driven, to a large extent, by gene duplication, retention, and divergence [1,2]. This is hypothesized to lead to both an increase in morphologi-cal complexity, via the evolution of novel features, and an increase in proteomic network complexity, through the establishment of new network interactions [3-5].
