Problem
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 ?
