DNA typically has 2 strands. It is structured as a double helix, meaning that it consists of two complementary strands that run in opposite directions. However, there are specific types of DNA, such as some viral DNA, that can be single-stranded (1 strand) or, in some cases, have more complex structures, but the most common form of DNA, especially in organisms, is double-stranded.
