The white wallaby in this image has a mutation that gives it a white coloring. how could this coloring affect its survival in its environment?

When changes happen in an environment. Many things can and will happen. If there was a gene mutation for the color of beetles, then that would affect their survival because the old color could have helped them hide and be camouflage. (however you spell it) If that is changed it could make them more out in the open, so predators could get them easier. Which would result in less beetles and more predators. Some examples are like the white wallaby, because of its environment it changes color to blend in and survive.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
