EXERCISE #4
INFORMATION:
GAPDH (glyceraldehyde 3-phosphate dehydrogenase)
-is an enzyme that participates in glycolysis, an important reaction in the process of cellular respiration
Table belows shows:
Similarity of this gene & the protein it expresses in humans versus other species.

-is an enzyme that participates in glycolysis, an important reaction in the process of cellular respiration
Table belows shows:
Similarity of this gene & the protein it expresses in humans versus other species.
a) Why is the percentage of similarity in the protein always higher than the percentage of similarity in the gene for each of the species?
The percentage of similarity in protein is always higher than percentage of similarity in genes because there are only 20 amino acids and there are many combinations of codons that can create the same protein. Also, if protein is not shaped correcty there can be mutaions due to protein being in specific in shape and size.
b) Draw a cladogram depicting the evolutionary relationships be-
tween all five species based on their percentage of similarity in the GAPDH gene.

tween all five species based on their percentage of similarity in the GAPDH gene.
Justification: This cladogram identifies how closely related chimpanzees are with humans. Also how humans and Elegans have a tremendous difference between each organism. Dos wll be in the middle between Elegans and humans.
