Example sentences for: erecta

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

  • 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.

  • 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]).

  • Neither coding nor non-coding sequences have experienced sufficient divergence to differentiate whether sequences 'conserved' between D. erecta and D. melanogaster result from functional constraint or shared ancestry (Figures 2, 4).

  • In the 30 fosmids, we predict a total of 164 protein-coding genes in non-melanogaster species (53 in D. erecta , 41 in D. pseudoobscura , 39 in D. willistoni , 31 in D. littoralis ) that form orthologous clusters with 81 D. melanogaster genes.

  • Of the species studied here, D. erecta is too closely related to D. melanogaster for comprehensive gene and cis -regulatory prediction.
