how is the order of nucleotides determined in a strand of a DNA

Answer 1

The order of nucleotides in a strand of DNA is determined by the sequence of the four types of nucleotides: adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of a DNA strand is determined by the specific pairing of these nucleotides, with A always pairing with T and C always pairing with G. The sequence of nucleotides in DNA is important because it provides the genetic code that determines the traits of an organism. The order of nucleotides is also important because it determines how DNA is transcribed into RNA and how proteins are ultimately synthesized.
