you analyze a dna sample and find that its base composition is 30 % a, 20 % t, 30 % g, and 20 % c. what can you conclude about the structure of this dna?

Respuesta :

The given DNA stand is a single stranded in place of a double strand as the correseponding base pairs are not equal to each other.

A does not equal T, and G does not equal C, this cannot be a double-stranded DNA molecule. It must therefore be a single-stranded DNA. The pairing of bases occurs in both RNA and DNA molecules. The bases that are present in DNA molecules are guanine, adenine, cytosine, and thymine while the bases that are present in RNA molecules are adenine, uracil, guanine, and cytosine. In a DNA molecule, the pairing is done in a way that A is always paired with T, while G is paired with C and in RNA the base T is replaced by U.
