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

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