In nature, these enzymes protect bacteria against phage infection by digesting the phage DNA when it enters the bacterial cell, acting as part of the restriction modification system. [129] In technology, these sequence-specific nucleases are used in molecular cloning and DNA fingerprinting.
Dynamic DNA nanotechnology focuses on forming nucleic acid systems with designed dynamic functionalities related to their overall structures, such as computation and mechanical motion. There is some overlap between structural and dynamic DNA nanotechnology, as structures can be formed through annealing and then reconfigured dynamically, or can ...
Plasmids with specially-constructed features are commonly used in laboratory for cloning purposes. These plasmid are generally non-conjugative but may have many more features, notably a "multiple cloning site" where multiple restriction enzyme cleavage sites allow for the insertion of a transgene insert. The bacteria containing the plasmids can ...
In 1995, the idea for DNA-based memory was proposed by Eric Baum [14] who conjectured that a vast amount of data can be stored in a tiny amount of DNA due to its ultra-high density. This expanded the horizon of DNA computing into the realm of memory technology although the in vitro demonstrations were made after almost a decade.

The main disadvantage of DNA nanoball sequencing is the short read length of the DNA sequences obtained with this method. [2] Short reads, especially for DNA high in DNA repeats, may map to two or more regions of the reference genome. A second disadvantage of this method is that multiple rounds of PCR have to be used.
