Example sentences for: antennae

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

  • This approach is especially powerful in a situation where the biological or molecular readout (putatively revealing the rhythmic process) is not robust - for example, the output from tim-luc or per-luc reporters in isolated antennae [ 10 13 ] .

  • The luc reporter was driven by a portion of the period (per) gene (its 5'-flanking sequences and those encoding the N-terminal 2/3 of the protein) in some cases or the 5'-flanking sequences of the timeless (tim) gene in the others; these molecular constructs were introduced into the D. melanogaster genome by germline transformation [ 32 18 33 ] . Reporter activity was sampled from an enzymatic reaction (luciferase oxidizing luciferin, present in the medium surrounding the antennae); the reaction produces a bioluminescent signal that is measured in counts per second once each hour [ 13 ] . One genetically based comparison made in this study involved the effects of the (normal) cry +allele compared with that of cry b, tested in LD 12:12 (12 hours of light followed by 12 hours of darkness, over the course of about 5-6 cycles per specimen).

  • Earlier studies have shown that the amplitude of rhythms in DD is reduced compared to LD [ 20 ] . These observations could reflect a weakening of synchrony between, for example, the two antennae within a well, or between multiple clock cells within a specimen.

  • This cryptochrome mutation produced dramatic effects on the phase of both reporters in DD: The mean-phase values were estimated to occur more than 7 hours earlier for cry b antennae compared to the cry +appendages.

  • Alternatively, the extreme difference in phase could indicate the loss of synchrony between multiple clock cells within the antennae consistent with the large decrease seen in the RI value.
