Bioinformatics

A sequence in the following set of reads is either correct and appears at least twice (possibly as a reverse complement); or incorrect with a single-nucleotide error and its Hamming distance is 1 with respect to exactly one correct read in the dataset (or its reverse complement). Show a list of all corrections in the format of "[old read]->[new read]". (Each correction must be a single symbol substitution.) You are required to show how you solve the problem, starting by showing the reverse complement of the reads.
