Question

Why do scientists studying evolutionary medicine in humans examine distantly-related species (e.g., yeast, nematode worms, frogs, plants, mice)? a) Clusters of orthologs common to humans and other species can be associated with the same functions b) They can be informative about how cells sense their environments c) Other organisms reproduce more quickly than humans, d) Shutting down genes is possible in more distantly related species but it is not ethically allowed in humans e) all of the above f) a, b, and c

Answer 1

Answer:

The correct answer will be option-F

Explanation:

The modern medical, molecular and genetic studies are performed on the model organism like C. elegans, mice and many others.

The reason for the studies is that the life span of these organisms is of short duration as compared to humans. These organisms are also made of cells which are sensitive to their environment as humans.

The studies have shown that this organism shows an orthology relationship in their genes due to the origin of the genes from the same ancestral genes.

Thus, option-F is the correct answer.
