Some genes encoding proteins that are essential to the survival of the organism are called highly conserved sequences.Which of the following is an example of one of these proteins?
A) cytochrome b
B) muscle structural proteins
C) carbohydrate hydrolyzing genes
D) skin pigmentation
E) keratin

Question

Quizplus · Accepted Answer

Cytochrome b is a protein that plays a critical role in the electron transport chain during cellular respiration, making it essential to the survival of all eukaryotic organisms. It is highly conserved across species, indicating its importance in maintaining cellular function. Muscle structural proteins, carbohydrate hydrolyzing genes, and keratin may also be important for survival but are not universally conserved like cytochrome b. Skin pigmentation is not a protein and is not essential to survival.
