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

For example, the junction between the aptamer and the Group I ribozyme in the aptazyme Th2P6 resembled the deletion variant td ΔP6-6; the aptazyme was activated by theophylline, while the splicing defect of the deletion variant at 3 mM magnesium was suppressed by 8 mM magnesium or by stabilization of a tetraloop sequence that capped the P6 helix [ 15 ] . Defects that poise a ribozyme between active and inactive conformers have previously been used to engineer effector-dependence [ 20 ] .
Magnesium had previously been shown to suppress structural defects in the td intron, and ligand-induced suppressions of splicing defects were examined by carrying out splicing reactions at either low (3 mM, stringent) or high (8 mM, permissive) magnesium concentrations [ 15 ] . Several of the constructs were either relatively inactive (e.g.
Similar results were obtained with cultures that contained the td gene divided by the aptazyme Th1P5 (Figure 4b).
Each of the successful aptazyme constructs was subsequently cloned into an interrupted thymidylate synthase gene in place of the parental td self-splicing intron.
5 mM) was added to liquid medium, bacteria grew almost as well as a control in which the parental intron was inserted into the td gene.
