What are the four bases that make up the rungs of the DNA ladder?

The four bases that make up the rungs of the DNA ladder are adenine, thymine, cytosine and guanine. They are often represented as A, T, C and G, respectively. When two strands of DNA form a double-strand helix, the bases pair up in the middle of the molecule. Hope this answers the question.

The four bases that make up the rungs of the DNA ladder are adenine (A), thymine (T), cytosine (C), and guanine (G), which pair specifically due to their shapes and charges to form the genetic code.
The Rungs of the DNA Ladder
The DNA ladder is composed of pairs of bases that form its rungs. The four types of bases that compose both strands of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). Adenine and guanine are classified as purines, with two rings of carbon atoms, while cytosine and thymine are pyrimidines, having a single ring. In DNA, these bases pair in a specific way due to their shape and charge: adenine always bonds with thymine, and cytosine always bonds with guanine. This complementary base pairing is crucial for DNA's function in genetic encoding.
The sequence of bases along the DNA molecules, held together by hydrogen bonds, determines the genetic code. When DNA replicates, the sequence of bases in one strand dictates the sequence in the new complementary strand, ensuring that the genetic information is accurately passed on during cell division.
