From: In and out of the rRNA genes: characterization of Pokey elements in the sequenced Daphnia genome
The 5′ length-variable region of Pokey elements from the Daphnia genome. Examples of the 5′ length-variable region containing A and C repeats are drawn to scale above the canonical element, also drawn to scale. Pokey A element names are in grey, and Pokey B element names are in black. The A repeats (approximately 200 bp) are similar to a sequence in the Daphnia intergenic spacer (IGS) while C repeats (approximately 50 bp) are similar to a sequence in the Daphnia internal transcribed spacer (ITS)2. Asterisks and bold type indicate variable positions in the aligned sequences. NCR, non-coding region. K = G or T, R = A or G, S = C or G, Y = C or T.
