About Bacterial DNA base sequence?

I'm trying to solve this question:





The template strand in bacterial DNA has the following base sequence:





5' – A T T C A G G T T T A A C G T G C A T G C - 3'








What is the amino acid sequence of the peptide encoded by this sequence?


Show the mRNA, with strand polarity correctly labeled, and indicate the amino and carboxy ends of the peptide.


Assume that consensus start and stop codons are used during translation of the mRNA encoded within this gene.








Thank you!

If this is the template strand, then the mRNA should be:





5' GC AUG CAC GUU AAA CCU GAA U 3'





AUG is the start codon.





Met-His-Val-Lys-Pro-Glu


There is no stop codon within the open reading frame for this peptide.
