Given a DNA sequence, which will be its mRNA?

[stonecoldgen]

And what will be the peptide sequence formed?

So the sequence is: ADN 3’- TAC-CGA-TAT-AGC-CGT-ATT -5’

so my guess is that it's AUG-GCU-AUA-UCG-GCA-UAA and the peptide sequence is: Start codon, alanin, isoleucine, serine, alanin, stop codon.

My question is: What do those 3's and 5's mean? How would the answer change if their positions were flipped?

3' and 5' refers to the carbon of the pentode sugar to which that particular Nitro base is attached to,
If it's flipped the sequence would be in reverse order.
