Because for the strands to form a double helix the base pairs have to match perfectly (adenine with thymine and cytosine with guanine) in DNA , and if a strand of RNA is paired with a split strand of DNA it goes adenine with uracil and cytosine with guanine (uracil replaces thymine)

The temperature of South Africa is extremely high which can be tolerated by the Nguni cattle due to its good characteristics. The Nguni cattle can bear extreme temperature, high intensity of light and resistance to parasites make it best suited for that environment.
