Cells only synthesize DNA from the 5′ to the 3′ end, and since double-stranded DNA is complementary, both strands cannot be replicated in the same way. How do cells handle this situation? View Available Hint(s) Cells only synthesize DNA from the 5′ to the 3′ end, and since double-stranded DNA is complementary, both strands cannot be replicated in the same way. How do cells handle this situation? The lagging strand is not synthesized at this point. The lagging strand must be synthesized in smaller units that are ultimately attached by the action of DNA ligase. Okazaki fragments are synthesized from both the leading and lagging strands. The lagging strand undergoes a conformational change to make a hairpin structure, which allows DNA synthesis in the proper order.

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
