Figure 4.

Repeat-derived sRNA clusters. (A) sRNA density plots at a high-copy repeat locus. Gray-shaded bars represent the degenerate repeat unit. (B) Northern blot hybridization with an oligonucleotide probe. Below the blots, RNA loading is shown by SYBR Gold staining. (C) sRNA density plot at a low-copy repeat locus. Colored bars that are not visible are not hidden; they are not large enough to see on the given scale. (D) Northern blot hybridization with oligonucleotide probes indicated in the illustration at top. Below the blots, RNA loading is shown by SYBR Gold staining. The possible structure of sRNAs bound to Twi7 is also shown. (E) Illustration of a putative telo-sRNA precursor derived from telomere transcription. (F) Northern blot hybridization with an oligonucleotide probe complementary to the G-strand of telomeric repeats. Below the blots, RNA loading is shown by SYBR Gold staining.
