First of all, DNA Sequence:-
TAC GAA CTT (G)GG TCC (that was a mistake in your question)
Now DNA gets transcribed to mRNA according to the rule of complimentary base pairing:-
AUG CUU GAA CCC AGG
Now, you have to look up the Codon Chart to find out the Amino Acids coded by each Codon.

Amino Acid Sequence:-
methionine- leucine- glutamic acid- proline- arginine
Deletion or addition of the nucleotides in the *multiples of 3* causes the deletion or addition of some amino acids in the polypeptide respectively, while deletion or addition of the nucleotides in the *non-multiples of 3* would result in a 'shift of the triplet sequence' of the codons changing the entire polypeptide from the point where mutation occurs.
RAM HAS RED CAP
Suppose these are the bases of the DNA.
If i insert B, then I, then G, in between the HAS and RED, it would change the triplet sequence.
RAM HAS BRE DCA P (← whole triplet sequence is disturbed)
RAM HAS BIR EDC AP (← whole triplet sequence is disturbed)
RAM HAS BIG RED CAP. (←BIG- multiple of 3 causes an amino acid to be added)
This is called as frame shift mutation
Substitution of a nucleotide causes a point mutation and results in the change of a single amino acid in the polypeptide. An example is Sickle Cell Anemia where a point mutation causes the change in the β-polypeptide chain of haemoglobin molecule.
