This might be a bad idea as a lot of animals live in wetlands
C , because Each strand of DNA acts as a template for synthesis of a new, complementary strand. Replication produces two identical DNA double helices, each with one new and one old strand.

What is the best desciption of the camouflage by natural selection?
Answer:
The correct answer is option D.
Explanation:
In the presence of SDS single band appeared, while in the absence of SDS two bands appeared. SDS or sodium dodecyl sulfate refers to an anionic detergent, which combines with amino acid side chains providing the protein a net negative charge. It dissociates the non-covalent bonds.
In SDS-PAGE, the separation of proteins takes place on the basis of their molecular weight. Options A and B are incorrect as only in the presence of SDS, the separation of protein subunits takes place. Option C is also incorrect as a protein containing distinct molecular weight cannot show single band.
Option D is correct as the presence of SDS supplements a bunch of negative charges to the protein, thus, charge is not the factor. Therefore, the proteins are distinguished on the basis of the molecular weight. Thus, identical molecular weight demonstrates a single band. In the non-presence of SDS, charge performs a function along with the molecular weight, therefore, two bands appear.
