Example sentences for: pai

How can you use “pai” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In contrast, a trans-methylated singlet PAI2 gene did not trans-methylate a naive allelic PAI2 gene within three generations [ 12 ] . Additional experimentation may eventually provide an answer to the question of what controls the efficiency of such epigenetic interactions.

  • The methylation status of the maize r1 genes and Arabidopsis PAI genes is altered upon paramutation [ 12 19 ] , while that of maize b1 is not [ 1 ] , except, in the non-conventional way, in the distal paramutation-control region of b1 [ 18 ] . Conversely, extensive exposure of a wild-type Arabidopsis SUPERMAN allele to a heavily methylated and transcriptionally silenced epiallele did not reveal any trans-silencing [ 20 ] .

  • Likewise, Arabidopsis PAI2 and PAI3 genes that have been trans-methylated by the PAI1/PAI4 locus do not transfer their methylation status to naive singlet genes [ 12 ] . In fact, there are few well-documented cases for the non-allelic relay of trans-silencing ability [ 11 24 ] . Does this amount to an operational difference between allelic (paramutation) and non-allelic (trans-silencing) interactions, or does it simply reflect a lack of data?

  • For example, an inverted repeat allele of the tryptophan biosynthetic gene PAI resident in the WS ecotype of Arabidopsis silences homologous PAI alleles, as well as unlinked PAI genes, from the Columbia ecotype [ 2 ] . Likewise, complex synthetic transgenes composed of PAI inverted repeats were able to trans-methylate homologous, yet non-allelic, target loci [ 12 ] . Similar events have been observed in other species [e.g.

  • Seac Pai Van Park, on the west coast of the island is an interesting natural preserve with aNatural History Museum.
