    By convention, when the sequence of a single strand of a DNA helix is presented without any other information, it is assumed to be the "sense" strand of the DNA region. This is the sequence that is used in DNA databases, for example. So, for 1. I will assume that this is the sense strand and so can be easily translated in a couple of ways. If the genetic code table that you have is of DNA codons, you can directly "translate" this sequence. If the table of the genetic code that you have is based on RNA codons, then you first should convert the given DNA sequence into an RNA sequence by replacing any Ts with Us:

    1. DNA 5' ATGAAACGGATTGGGCCA 3'

    RNA 5' AUGAAACGGAUUGGGCCA 3'

    Amino acids: Met-Lys-Arg-Ile-Gly-Pro

    2. Here, I'm going to assume that the sequence given is the "coding" or "template" strand of DNA that must first be "transcribed" into an RNA sequence:

    DNA: 3' TACCGACTATGCTTT 5'

    RNA: 5' AUGGCUGAUACGAAA 3'

    Amino acids: Met-Ala-Asp-Thr-Lys
