After mutagenesis and screening take place, you have found a mutant that is able to grow in soil with high copper content. Protein analysis shows that the concentration of metallothioneins in the mutant is different from that in normal plants. How does the concentration of metallothioneins likely differ in the mutant relative to the normal plant?

Question

Quizplus · Accepted Answer

Since the mutant is able to grow in soil with high copper content, it is likely that the mutant has a higher concentration of metal-binding proteins, such as metallothioneins, than normal plants. Therefore, the concentration of metallothioneins is greater in the mutant.
