The loop region of the beacon is designed to bind specifically to a target nucleic acid. Thus, in the presence of the target nucleic acid, the stem region of the beacon becomes separated, releasing the fluorophore from the quencher such that active fluorescence can be observed.

A chi-squared test (symbolically represented as χ2) is basically a data analysis on the basis of observations of a random set of variables. Usually, it is a comparison of two statistical data sets.

The chi-square test is used to estimate how likely the observations that are made would be, by considering the assumption of the null hypothesis as true.

When we consider, the null speculation is true, the sampling distribution of the test statistic is called as chi-squared distribution.
