Answer:
Correct Answer: D
Solution:
We know that DNA molecules are found primarly in the nucleus of the cell but RNA molecules are found outside the nucleus.
By heating, its special structural arrangement is changed irreversibly, resulting in the conversion of enzyme into a fibrous or insoluble form.
Due to this irreversible change, enzymes lose their specific activity when heated.
