This is attributable to different causes: 1) the well preserved state of the mummy and the consequent high copy number of endogenous DNA remaining; 2) the protection offered by the body (samples were taken from inside the intestines); 3) the precautions adopted during sampling and subsequent laboratory investigations [24].
In this paper, we shall routinely use the term 'growth rate', rather than 'flux', since we have measured differences in growth rate consequent on reducing the copy number of individual genes from two to one in diploid yeast.
This contradicts a possible indirect E1A siRNA-mediated protective effect (which may occur following blockage of viral DNA replication), and a consequent decrease in the copy numbers of other genes, such as the adenovirus death protein (ADP) gene, which is required for efficient cell lysis and virus release (Tollefson et al., 1996).
The proposed scenario for the fate of transferred genes in bacteria based on these observations includes their uptake, duplication, rapid diversification of gene copies by mutations, and consequent fixation of the "best" copies and elimination of other duplicates.
Although rapid onset (11 13 weeks) of multifocal mammary tumors was observed in the majority of activated neu transgenic mice, this mutation has never been observed in human cancers, which only present amplification of the HER2 gene copy number and consequent overexpression of HER2 protein on the cell membrane.
One hypothesis is that an increase in mtDNA copy number and the consequent increase in the number of tRNAGlu molecules would compensate for the defect and may overcome the functional consequences of the homoplasmic tRNA mutation in skeletal muscle.
The loss of performance has been fully described consequent to the use of zero-copy memory.
Most LCSCs displaying high levels of EGFR expression and activation (LCSCs 3, 4, 5) harbored increased copies of EGFR gene (>8), suggesting that increased EGFR gene copies may contribute to overexpression and consequent activation of the receptor (Table 1).
A loss of copy number of Daple DNA, and consequent downregulation of gene expression and function was noted in the primary tumors, predominantly among the tumors with CIN.
SINEs were selected as the target DNA owing to their abundant copy number in genomes and the consequent high level of sensitivity and specificity which they offers [ 12].
