Example sentences for: buchnera

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

  • We applied a conservative criterion for presence of a promoter in Buchnera, by requiring retention of as few as four of these six nucleotides with a separation of 16-18 nucleotides.

  • The ancestral genome was therefore divided into a total of 306 fragments, just over half of which were retained in the Buchnera genome, and there are 306 junctions between these fragments on the circular chromosome (Figure 3).

  • These hypothetical losses of regulatory regions from the reduced genome of Buchnera are based on levels of sequence similarity with the known consensus sequence in modern E. coli.

  • Typically, bacteria possess multiple rRNA operons, each containing all three genes; the Buchnera ancestor is inferred to have possessed at least five operons and modern E. coli has seven.

  • Only two of the 560 protein-coding genes that show clear orthology between E. coli and Buchnera would have been removed (due to absence from both Vibrio cholerae and Yersinia pestis ). The two genes ( dnaC and dnaT ) are linked in both Buchnera and E. coli and were retained in the ancestor.
