Example sentences for: trnas

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

  • Although the region is not bracketed by IS elements or tRNAs that are characteristic of pathogenicity islands (PAIs), it bears features that are similar to the putative PAI identified in the B. anthracis plasmid pXO1 [ 20 ] . Bacterial sequences with similarity to the B. anthracis cap genes are present in sequence databases.

  • We searched for new tRNA genes using the program tRNAscan-SE [ 32] and Sim4 alignments to known tRNAs: 290 are annotated in the euchromatin (Table 2).

  • The Buchnera gene inventory, consisting of only 564 ORFs, 32 tRNAs and a single copy of each rRNA gene, is essentially a subset of that of E. coli [ 8].

  • E. coli has 86 tRNAs, and most of these appear to be present in the ancestor (the parsimony criterion for presence of a tRNA in the ancestor, based on distribution in sequenced genomes, is somewhat unreliable because of sequence homology among different tRNA genes).

  • The production of tRNAs corresponds to the frequencies with which the different codons are present in their protein coding genes.
