Write a Python function named count

_

nucl

_

freq that accepts a list of DNA sequences, dataList, where each sequence is represented as a string of nucleotides

('

','

','

','

') .

Your function should calculate the frequency of each nucleotide in each column across all sequences. The function should return a list of dictionaries, where each dictionary corresponds to a column in the input data and maps each nucleotide to its frequency count in that column.
