Since retroposed gene copies most often lack regulatory regions and will not be initially expressed, they are believed to degenerate in most cases [ 2- 4].
In addition, cells with chromosome 12 polysomy, most often three or five copies, were detected in 70% of MSS-type colorectal carcinoma samples, 50% of MSI-type samples, and 31% of adenoma samples.
It should be noticed that the average number of 16S rDNA copies per bacterial cell is 4.2, and the nosZ gene most often carry a single copy (Palmer et al. 2009).
In fact, 14q deletions are most often associated with significant copy number variations that occur during adenoma-to-carcinoma conversion (Tsafrir et al., 2006).
Fax machines produce copies that most often cannot be scanned, and they are losing the value that they once had for urgency.
These are remnants of IE-A introns: highly degenerated, partial copies that most often only consist of a small 50-nt motif (motif-C, supplementary figs. S2 S5, Supplementary Material online), having lost both splice sites and all other motifs crucial for the splicing process.
Focusing on this single gene, either as a single-copy or, most often in animals, duplicated, we have identified dozens of intron positions.
FLCN is a tumour suppressor gene, and associated tumours arise when both copies are inactivated most often through "second hit" somatic mutations.
Other groups have reported a lower rate of copy gain, corresponding most often to polysomy [ 13, 21- 23].
The copy-number state of the call also affected how often overlap was observed, with copy-state 1 least often being found to overlap any calls in the Sanger data, and copy-state 0 most often found to overlap calls (Additional file 1: Table S4).
