Question

A researcher sequenced a portion of a bacterial gene and obtained
the following sequence, beginning with the start codon, which is
underlined:
ATG CCG GAT TAC CCG GTC CCA AAC AAA ATG ATC
GGC CGC CGA ATC TAT CCC
The bacterial strain that contained this gene has been maintained
in the laboratory and grown serially for many generations. Recently,
another person working in the laboratory isolated DNA from the
bacterial strain and sequenced the same region. The following
results were obtained:
ATG CCG GAT TAT CCG GTC CCA AAT AAA ATG ATC
GGC CGC CGA ATC TAC CCC
Explain why the differences in the sequences may have occurred.
