Thus, while essentially all gene conversion tracts in the GFP-LacI control cells contained at least two mutations, acceleration of diversification by either tethered VP16 or HIRA was accompanied by a diminished number of nucleotide substitutions per tract.
In parallel, few studies have focused on the diversification of the group, being either at the scale of all angiosperms [ 24] or within families [ 25, 26].
These features raise the possibility that there has been either a diversification of mitotic functions in the trypanosome Kinesin-13 proteins, or a specialisation of roles for specific microtubule sets.
Consistent with evolutionary expectation, our quantitative analysis suggests that paralogous transcription factors have survived extinction in part, either through diversification of their DNA binding site motifs or through alterations in their tissue-specific expression levels.
While recent investigations have focused on the diversification of herpetofauna groups that are either endemic or typical of the Cerrado [ 12, 16], or broadly distributed across all biomes [ 5, 9, 17], no study to date addressed lizard taxa endemic to the biomes located at the extremes of the dry diagonal, namely the Chaco and Caatinga.
Hence, the success of Late Triassic Rhynchocephalia suggests either a rapid diversification of the clade or alternatively an older unknown history during the Early and Middle Triassic [ 24- 26].
Whether this leads to retention of function of duplicated genes or to functional diversification either at the level of gene expression or protein function remains to be determined.
Diversification allows them to use their resources efficiently: the same networks of people and lorries can be employed in the import of either tobacco or class A drugs.There are exceptions.
The high sequence diversification of fungal APs has been caused by either adaptation or drift.
In Mexico, current law initiatives assume that the spread of transgenes into centers of crop origin and diversification can be either prevented or reversed if commercial release of GMVs is restricted to areas of industrialized agriculture.
