Because of the small spatial scale of a major chimera-generating mechanism (predominantly intramolecular and <10 kbp), such chimeric molecules are a severe impediment to development and application of larger insert (3 10 kbp) libraries.
The major fungal chimera components are MGL LINE retrotransposon and WEIRD.
It was also possible to exclude two other potential mechanisms as playing a major role in chimera formation.
In FUS-Npl3 chimera, major RNA-binding domains of FUS (amino acids 360 526) were replaced by RRMs (yRRM1 and yRRM2) of the yeast RNA-binding protein Npl3.
Here, we characterize the major types of chimeras formed by carrying out an MDA whole genome amplification from a single E. coli cell and sequencing by the 454 Life Sciences method.
Two major mathematical models – ternary chimera switch (TCS) and cascading bistable switches (CBS) - that both focus on the miR-34/SNAIL/miR-200/ZEB1 network, have been proposed to elucidate the EMT dynamics, but a detailed analysis of how well either or both of these two models can capture recent experimental observations about EMT dynamics remains to be done.
In cluster 2, major transcriptional up-regulation in chimera was observed at the slug stage, while a peak in expression in the chimera was observed in the aggregate stage in cluster 3.
We do not consider chimeras as a major contributor to unassignable tags because, as our protocol amplifies short DNA sequences with a negligible likelihood of chimera formation [ 31].
Moreover, they contribute extensively to somatic chimeras, presenting a major discrepancy with the embryo deletion analysis.
These "chimeras" are a major problem in turtle systematics, especially in paleontological studies where the inclusion of broadly paraphyletic OTUs is a recurring phenomenon [ 10].
The feasibility of the GEMM-ESC production approach depends on reliable procedures and robust quality controls, including (i) ESC culture procedures that guarantee maintenance of pluripotency; (ii) monitoring of the genomic stability of ESCs; (iii) procedures for routine production of chimeras with a major contribution of the GEMM-ESCs to different tissues.
