---Question: A bioinformatician is analyzing a dataset of DNA sequences, each represented as a point in a 3D space where each coordinate corresponds to the frequency of a nucleotide (A, C, G, T). If three such sequences correspond to the points $(1, 2, 3), (4, 5, 6),$ and $(7, 8, 9)$, find the coordinates of the fourth point that would form a regular tetrahedron with integer coordinates, ensuring all edges are of equal length. - Appfinity Technologies
