1. A is the only sequence complimentary to the given one.





2. I don't like the question, but the only answer that makes any sense at all would be D.





3. If the heterozygote has a phenotype different than either homozygote, you must have a situation of incomplete dominance (C).
Reply:A. AGT





D.Okazaki fragments





C. incomplete dominance
