Example sentences for: erecta
How can you use “erecta” in a sentence? Here are some example sentences to help you improve your vocabulary:
From the results of this screen, we estimated the average number of unique hits per library per species to be 4.1 for D. erecta , 3.2 for D. pseudoobscura , 2.2 for D. willistoni and 2.9 for D. littoralis . These figures indicate that these libraries have fewer unique hits than the expected approximately 5× coverage.
To amplify gene-specific STSs, D. erecta, D. pseudoobscura, D. willistoni and D. littoralis genomic DNA was isolated from adult flies and used as template for PCR with degenerate primers.
The ratio of conserved sequences that are coding relative to non-coding is 1.36 for comparisons with D. erecta , but increases to 2.21 for comparisons involving D. pseudoobscura and approximately 3.5 for comparisons involving D. willistoni or D. littoralis .
As shown in Figures 2and 4, a substantial proportion of non-coding sequences are conserved in Drosophila , especially in pairwise comparisons between D. melanogaster and D. erecta . Levels of conservation appear to plateau in more divergent comparisons, with a tendency for D. pseudoobscura to show higher levels of non-coding conservation relative to D. willistoni or D. littoralis in pairwise comparisons with D. melanogaster . Few, if any, non-coding sequences are conserved between D. melanogaster and A. gambiae (Figure 4, see also [ 23]).
In an accompanying paper, C. Bergman et al . [ 65] surveyed sequence conservation in approximately 0.5 Mb of the D. melanogaster genome containing 81 genes using comparative data from four Drosophila species ( D. erecta, D. pseudoobscura, D. willistoni and D. littoralis) . Their comparison to our D. melanogaster annotations detected no genes conserved in other species that were missed in Release 3 [ 65].
