Python code not working, please check my code. Here is the question it is based off: Building and using DNA Motifs Background Sequence motifs are short, recurring (meaning conserved) patterns in DNA that are presumed to have a biological function. Often they indicate sequence-specific binding sites for proteins and other important markers. However, sometimes they are not exactly conserved, meaning some mutations can happen in a motif in a particular organism. Mutations can be DNA substitutions/deletions/insertions. Therefore, sequences are usually aligned and a consensus pattern of a motif is calculated over all examples from organisms. The following are examples of a transcription factor binding (TFB) site for the lexA repressor in_ E. Coli _located in a file called lexA.fasta: >dinD 32->52 aactgtatataaatacagtt >dinG 15->35 tattggctgtttatacagta >dinH 77->97 tcctgttaatccatacagca >dinI 19->39 acctgtataaataaccagta >lexA-1 28->48 tgctgtatatactcacagca…
