Which type of DNA is a non-canonical structure that forms when a single-stranded DNA molecule folds back on itself and forms base pairs with itself?
This type of DNA is known as the hairpin DNA.
It is a non-canonical structure. It forms when a single-stranded DNA molecule folds back on itself and forms base pairs between the complementary sequences within the same strand.
This type of structure is common in regulatory regions, DNA replication, and the gene expression process.
They also occur in RNA molecules.
