Question

A consensus sequence is a series of bases or types of bases commonly found at a specific position in the genomes of multiple individuals. The two types of bases are purines (R) and pyrimidines (Y). The following table shows the nucleotide sequence of a region of gene X from six different individuals. Nucleotide positions are labeled 1 through 7.

A A T A G T A

A A T T A T A

A C C T G T T

A A C T A T T

A A A A G T A

A C A T A T A

Compare the sequences of all six individuals to determine the consensus sequence for this region of gene X.
