Problem 1 (15 points)

You are given the following DNA sequence, which is believed to contain a small protein-coding gene.

GGAGGCGTAA AATGCGTACT GGTAATGCAA ACTAATGG

  • If this sequence is fully transcribed (used as a coding strand), what is the corresponding mRNA sequence?

  • Which region of the mRNA do you think can be translated into a protein (hint: Can you identify the start codon and stop codon from the mRNA sequence?)

  • What is the protein sequence encoded by the gene?

  • If the reverse-complementary strand of the DNA sequence is also tran-

    scribed, what will be the mRNA sequence?

  • Do you think this reverse-complementary strand can encode a protein by itself ?
