Properties of terminators. (A) Base content surrounding the 3457 optimal nonoverlapping Hrp1 binding sites in terminator regions (≤150 bp upstream of CPA site). Colors indicate the base at the corresponding position, from 25 bp upstream of to 25 bp downstream from the motif match. (B) Alignment of RNA-seq reads corresponding to poly(A) sites (Nagalakshmi et al. 2008) on both DNA strands for convergent intergenic regions (Conv.) and elsewhere in the genome (Else.). Data are aligned to sense poly(A) sites and include all poly(A) sites in the genome with at least two reads. The data represent the average read count of all aligned loci and are smoothed over a 5-bp window.
