8.The following table contains DNA-sequence information compiled by Marilyn Kozak (1987). The data

9.   The following table lists α-globin and β-globin gene sequences for the 12 nucleotides preceding the start codon and the first nucleotide following the start codon. The data are for 16 vertebrate globin genes reported by Kozak (1987). The sequences are written from -12 to +4 with the start codon underlined.

Use the data in the table to
a.   Determine the consensus sequence for the 16 selected α-globin and β-globin genes.
b.   Compare the consensus sequence for these globin genes to the consensus sequence derived from the larger study of 699 vertebrate genes in Problem 8.
