A mutation of c to t in position 3 and another of G to A in position 7 results in the production of a different sequence of ammino acids work out the new sequence and suggest why it might change the function of the new protein

I get the sequence of

ATAAGCTTT

in Mrna
AUAAGCUUU
wHICH

AUA = lle
AGC = ser
UUU = PHENYLALANINE

The reason I give is that mutant strands lack meth and no protein to syntheis

I look forward to your critique

sorry have you taken the original DNA structure then altered the position 3 & 7 as the mutation, then altered to the mRNA structure, to get the amino acids, it looks like you have done it twice!!!
