While it is apparent that local extinctions may further inhibit the accumulation of copying errors in a structured population, understanding the magnitude of this effect requires systematic investigation.
Thus, a larger accumulation of copying errors in a metapopulation signifies a faster rate of cumulative culture change per transmission event.
Here, we analyzed the accumulation of copy number variations (CNVs) using fluorescence in situ hybridization in cancer cases and explored factors associated with the detection of CNVs in tumor-free men.
Accumulation of several copies of duplicate hydrophobin genes from a single copy of ancestral sequence may have resulted in the variation in numbers of hydrophobin genes in the different fungi.
(2013) specifically demonstrated that selection had acted on a series of duplication events to favor the accumulation of additional copies of AMY2B, resulting in an average sevenfold copy number increase in dogs relative to in wolves, and that this increase corresponds to higher pancreatic AMY2B expression as well as higher serum amylase activity.
The accumulation of Galileo copies after the generation of inversions 2j and 2q7 (Table 3) indicates that Galileo is (or has been recently) active in the genome of D. buzzatii.
6 The reaction results in the accumulation of 10 copies of target and simply requires a laboratory water bath or heating block to maintain a constant temperature of 60 65°C, making it particularly suited to lower-technology settings.
According to the TE evolutionary cycle, the TE history could start from HT events, followed by the initial transpositional burst in the new host, and then the accumulation of defective copies along with host-directed epigenetic silencing [ 40].
In both of these cases, these elements were much more fragmented than human L1 insertions of similar age, suggesting that DNA loss in the form of large deletions is counteracting the accumulation of retrotransposon copies in fish and reptiles, thus limiting the expansion of the sizes of these genomes.
Hepatitis C virus (HCV) is a plus-strand RNA virus that replicates by amplification of genomic RNA from minus strands leading to accumulation of almost one thousand copies per cell under in vitro cell culture conditions.
This process may conceal the accumulation of divergence between copies.
