CCTGC
Explanation:
Adenine (A) and Thymine (T) are base-pairs whilst Cytosine (C) and Guanine (G) are base-pairs as well. Although they only go in the order A-T and C-G, you will never see Adenine and Cytosine together on a DNA strand.
Answer:
Genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. Organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment.
Explanation:
Genetic variations are important because a diverse gene pool is good for long-term survival of a species since the environment is always changing, so the diversity of DNA offers the most fit of the species a better chance of surviving because they are most adapted to the constantly changing environment.
