Concept explainers
To determine: The factors that might cause the apparent contradiction that gene that function as normal or wild-type in one primate may function as a disease-causing gene in another primate.
Introduction: The difference in the genome of the human and chimpanzee lead to an apparent contradiction that a gene may act differently in two different organisms. It could be normal or wild-type in one while disease-causing in another one.
To determine: Whether the given contradiction in the question is rare or common.
Introduction: The behavior of some genes differs from species to species. A gene may be normal and wild-type in one species, while in other species it may be a disease-causing gene.
To determine: The effect of the finding of gene contradiction on the comparative genomics to identify and design therapies for disease-causing genes in humans.
Introduction: Comparative genomics is a field of research in which the genome of the organisms is analyzed and compared. The genome analysis has become feasible due to the availability of several completely sequenced genomes.
