Question

what could explain the difference observed in the two enzymes?
a) all of the above
b) gene amplification
c) chromosomal rearrangement
d) a base change in the dna

Explanation:

• A base change in DNA (point mutation) can alter the amino acid sequence of an enzyme, changing its structure/function.
• Chromosomal rearrangement can disrupt or relocate the enzyme's gene, leading to a non-functional or altered enzyme.
• Gene amplification can increase enzyme production, or if the amplified gene has mutations, lead to altered enzyme forms.

All these mechanisms can cause differences between two enzymes.

Answer:

a) All of the above
