The Genes That Code for the Enzyme Lysozyme from a Number

Multiple Choice

The genes that code for the enzyme lysozyme from a number of organisms whose diets comprise mostly leaves and grass were sequenced.Comparisons of the gene sequences revealed that

A) the rate of nonsynonymous mutations is higher than that of synonymous mutations in most lineages.
B) a recent common ancestor is necessary for organisms to develop very similar adaptations.
C) the sequences of bovine (cattle) lysozyme and langur lysozyme are highly divergent.
D) the number of changes in lysozyme uniquely shared by cattle, langur, and the hoatzin was high.
E) none of the changes in lysozyme were adaptive.
