^a 4,407 peaks.

^b “Best” quality peaks are the 366 peaks that increased in frequency in each round of SELEX.

^c “Good” quality peaks are the 932 peaks that increased in frequency in the final round of SELEX and had a fourth round frequency greater than 2,800.

^d “Moderate” quality peaks are the 269 peaks that increased in frequency in the final round of SELEX and had a fourth round frequency less than 2,800.

^e “Poor” quality peaks are the 2,827 peaks that increased in frequency only in the first round of SELEX.

^f “Worst” quality peaks are the 13 peaks that decreased in frequency in the first round of SELEX.

^g Control peaks are six pooled groups of 366 randomly selected positions in the chromosome of strain CFT073.
