Use the following mRNA codon key as needed to answer this question:
GCC Alanine
AAU Asparagine
CCU Proline
GGA Glycine
UGG Tryptophan
UGA "Stop" (no amino acid)
GAA Glutamic acid
GAG Glutamic acid
AGG Arginine
CCC Proline
CAU Histidine
The following DNA sequence (coding strand) occurs near the middle of the coding region of a gene.
DNA:
50
mRNA:
55
5'-AATGAATGGGAGCCTGAAGGAG--3'
50
The corresponding mRNA sequence is shown below. Note that the coding strand of DNA has the same sequence as
the mRNA, except that there are U's in the mRNA where there are T's in the DNA. The first triplet of nucleotides
AAU (underlined) is in frame for coding, and encodes Asparagine as the codon table above indicates.
