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

Metallothioneins are metal-binding proteins that are involved in detoxification of heavy metals such as copper. The fact that the mutant can grow in soil with high copper content suggests that it may have an increased concentration of metallothioneins to aid in copper detoxification. Therefore, the concentration of metallothioneins is likely greater in the mutant relative to the normal plant.
