Desertification extends beyond the expansion of existing deserts to include land degradation due to human activity in drylands. Land degradation destroys or reduces the productivity of the soil, and is caused by excessive and unsustainable activities such as deforestation, overgrazing, poor land management, soil salinization, and soil erosion.
Sure hope this helps you :D
The correct answer is four base pairs.
BamHI is endonuclease meaning that it has the ability to cut DNA at specific target site. The recognition sequence of BamHI is 5'-GGATCC-3 and it cleaves it after the first G. Sticky ends are formed as a result of that cleavage remaining a four-base 5' overhang in one molecule and a complementary 5' overhang in the other. These ends are can be joined back together by an enzyme called ligase.
Im pretty positive the answer is D
