DNA is described as which type of molecule?

Explanation:
DNA is a double-stranded molecule that forms a right-handed double helix. Two long polynucleotide chains run in opposite directions and are held together by hydrogen bonds between complementary bases (A pairs with T, G with C). This double-stranded, base-paired arrangement enables accurate replication and transcription because each strand can serve as a template for making its partner. While some DNA molecules can be circular (as in many bacterial plasmids), the standard description for DNA in biology is that it is double-stranded; single-stranded DNA occurs in specific contexts, and triple-stranded DNA is not the typical form of cellular DNA.
