  Here we show that the Weak Basis Transformation is an appropriate
mathematical tool that can be used to find texture zeros in the quark mass
matrix sector of the Standard Model. So, starting with the most general quark
mass matrices and taking physical data into consideration, is possible to
obtain more than three texture zeros by any weak basis transformation. Where
the most general quark mass matrices considered in the model, were obtained
through a special weak basis wherein the mass matrix $M_u$~(or $M_d$) has been
taken to be diagonal and only the matrix $M_d$~(or $M_u$) is considered to be
most general.
