How can you use “proto-splice” in a sentence? Here are some example sentences to help you improve your vocabulary:
The finding of a similar motif in rRNA genes for which there is neither a requirement to incorporate amino acid phase distribution nor to invoke exon-shuffling provides support for the idea that a proto-splice site for intron insertion not only exists in Euascomycetes rRNA but also may exist in pre-mRNA genes.
With our data set of 49 (two diatom-specific introns were excluded from this analysis) different spliceosomal intron sites in the SSU and LSU rRNAs of Euascomycetes (alignment available at http://www.rna.icmb.utexas.edu/ANALYSIS/FUNGINT/(for registration details please see http://www.rnq.icmb.utexas.edu/cgi-access/access/locked.cgi), we first tested for the presence of a proto-splice site flanking the introns [ 12 ] . In this chi-square analysis, the null hypothesis specified that nucleotide usage in 50 nt of exon sequence upstream and downstream of the different intron insertion sites was random and dependent on the nucleotide composition of Euascomycetes SSU and LSU rRNA sequences in general.
Our analysis of 100 nt of exon sequence flanking spliceosomal introns in Euascomycetes rRNA shows significant support for a G - G or AG - G proto-splice site (Fig.
Previously, we found evidence for the proto-splice site, AG - G, in Euascomycetes rRNA with the greatest support for the G nucleotides (p < 0.001 [ 12 ] ). The addition of 18 new Euascomycetes SSU and LSU rRNA insertion sites in the new analysis supports this finding (see Fig.
