The Next Questions Refer to the Following Table, Which Compares

question 19

Multiple Choice

The next questions refer to the following table, which compares the % sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (e.g., Intron I is the one closest to the promoter) . The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.
% Sequence Homology

-Which of these four gene parts should allow the construction of the most accurate phylogenetic tree, assuming that this is the only part of the gene that has acted as a reliable molecular clock?

• A) Intron I
• B) Exon I
• C) Intron VI
• D) Exon V
