As the mutation occurs in G, a purine to T,a pyrimidine- it is a transversion type of point mutation.
In the DNA sequence - ATGCGTGGA-, the mRNA having -AUG- codon in first,codes for the amino acid Methionine,which is the START CODON. So when this codon is present,the translation will start. But when the third G is mutated to T; the mRNA will have the codon sequence -AUU-, which codes for Isoleucine. So, from there the translation will not start.
