FIG 4.

Images of Northern blots for confirmed sRNA candidates from computational prediction. The total RNA samples were extracted from D. radiodurans cell cultures at exponential phase (OD₆₀₀ = 1). The expressions of predicted sRNAs were confirmed, and the sizes of the transcripts were estimated relative to the phiX174/HinfI ladder. Some of the images of the ladder and the sRNA lanes are cut from the same gel in different parts, with the contrast being adjusted to show a clearer image.
