PATHOLOGY

Detailed explanation-1: -Paul Nurse demonstrated that a strain of yeast with a defective gene could use the human version of that gene to repair itself. That we not only share a common genetic code with other organisms, but that we actually share specific genes, is powerful evidence of our common ancestry.

Detailed explanation-2: -Yeast possesses 23% homologous genes to humans; therefore, it is considered as a useful model for gene function studies (2).

Detailed explanation-3: -The advantage of using yeast is that is an amenable organism, easy to manipulate, and for which many genetic tools have been created, such as the yeast deletion pool that enables genome-wide genetic and chemical screenings [9].

Detailed explanation-4: -Characteristics of the Genetic Code The genetic code is universal. All known living organisms use the same genetic code. This shows that all organisms share a common evolutionary history. The genetic code is unambiguous.

Detailed explanation-5: -The first reason is that we all came from a common ancestor. In other words, we all started out with the same DNA way back when. The different animals we see today are due to lots of small changes that have happened in living things since then.
