Homologous proteins such as hemoglobin from different organisms do NOT:
A) have nearly identical lengths.
B) share little sequence homology with other proteins with similar function (e.g., myoglobin).
C) share a significant degree of sequence similarity.
D) perform the same function in different organisms.
E) have sequence identity in direct correlation to the relatedness of the species from which they were derived.

Question

Quizplus · Accepted Answer

The statement "share little sequence homology with other proteins with similar function (e.g., myoglobin)" is incorrect as homologous proteins share a significant degree of sequence similarity, including with other proteins with similar function. The other choices, A, C, D, and E, are all correct statements about homologous proteins.
