Figure 3From: Guanine quadruplexes are formed by specific regions of human transposable elementsThe density of PQSs inside TEs and in TEs vicinity. The number of PQSs per 100 bp of zone located inside, upstream and downstream of LINE-1 (a), HERV (b), SVA (c) and Alu elements (d). For each element type PQS in plus strand (upper row) and minus strand (lower row) are shown. We analyzed either all elements (left figures) or only full-length elements (right figures).Back to article page
