The ratio between the two forms of DsrA (F/T) sRNA varies in a temperature-dependent manner, with relatively more T formed at higher temperatures. At low temperature, the F form of DsrA outnumbers the T form.

An increasing number of RNAs have been recently shown to possess regulatory functions similar to those of proteins. In bacteria, these regulatory RNAs are usually noncoding and are short size (50–500 nts) transcripts that are often referred to as small RNAs (sRNAs) [1], [2].
