What is the correct mRNA transcription of the following DNA sequence? ATGGCACCTTAC A. UACCGUGGAAUG B. CATTCCACGGTA C. AUGGCACCUUAC D. CAUUCCACGGUA

Explanation:

In a DNA molecule, Adenine forms hydrogen bonds with Thymine and Cytosine forms hydrogen bomds with Guanine.

However in mRNA, Thymine becomes Uracil (T => U)

Therefore every A in the DNA sequence becomes U,

every T in the DNA sequence becomes A,

every C in the DNA sequence becomes G,

every G in the DNA sequence becomes C.

The answer is A.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

the "dirty dozen" chemicals banned in an international treaty are formally known as persistent organic pollutants, or pops. the united nations environment program provided this background on what they are and what they can do to humans and wildlife.
