The luciferase transgene can be genetically inserted at the first intron of a target gene to act as a surrogate for the gene's endogenous expression in cells and transgenic mice. Alternatively, promoter sequences can be excised and/or amplified from genomic sources or constructed de novo and ...
How and why bioluminescenceoccursis not fully understood; however, in the undersea realm, it appears to be used in a variety of interesting and ingenious ways. The most commonly observed form of bioluminescence in the sea is the pinpoint sparking of light at night that can create cometlike tr...
Based on a large dataset and extensive knowledge from the literature, we show that the ability to bioluminesce may be strongly driven by habitat. We hypothesize that this is probably related to differences in optical properties between pelagic and benthic environments (Fig. 4). While more than ...
B. Bioluminescence can be used to achieve various and sometimes seemingly opposite goals such as frightening away predators or luring prey. C. Bioluminescence can be used by some sea creatures as a form of communication or as a means of identifying an appropriate mate. D. The majority of biolu...
The amount of luciferase produced in vivo can be quantified by photons as a measure of promoter activity. Bioluminescent imaging offers the advantage of identifying mice with tumors and specifically measuring tumor cell response to treatment non-invasively, allowing each mouse to be its own control....
Fishes control the output of light intensity using different mechanisms which can be categorized as being under control of hormonal or neuronal pathways. Usually, neural control allows fast and direct response to the photocytes while endocrinal systems allow to control the lig...
When this fluctuation is averaged over several cycles in order to obtain an approximated timing of time series increase, a phase can be computed via waveform analysis. A waveform analysis72 was carried out on biological and floor orientation data, by subdividing time series on the length of the...
A. Bioluminescent creature uses a substance called luciferin and an enzyme to produce light in a biologically driven chemical reaction. B. Bioluminescence can be used to achieve various and sometimes seemingly opposite goals such as frightening away predators or luring prey. ...

distance. Slowly fading green blobs or pulses of light can be seen coming from the organisms within, often from gelatinous creatures. This type of light display may be used to stun, disorient, or lure prey. Like a wide-eyed deer caught on a road and dazed by headlights, undersea creatur...
