Example sentences for: trnas

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

  • When E. coli Bl21(DE3), a strain that did not express additional rare tRNAs, was transformed with the cloned T. acidophilum ATPase A subunit, no additional protein bands were observed in extracts of induced cells (not shown).

  • 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.

  • Currently, only the type I tRNAs [ 81 ] are included here; the tRNAs are collected in 19 functional subgroup alignments and one total type I alignment.

  • 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].
