DNA comprises two polynucleotide strands twisted around each other in the form of a double helix (Figure 2.1). Each strand has a sugar phosphate backbone linked from the 5′ and 3′ carbon atoms of deoxyribose. At the end of a strand is either a 5′ phosphate group (5′ end) or a 3...
It is important to point out that although there are many different means for topologically modifying DNA molecules, for data storage applications enzymatic nicking (i.e., creating a single-bond cut in the DNA sugar-phosphate backbone via an enzyme) appears to be the most specific, efficient, ...
Topoisomerase can destroy or link the sugar phosphate backbone and produce transient single or double strand breaks of DNA, thus changing the DNA topology. The action mechanism can be summarized into three steps: disconnection, crossing and connection. There are two kinds of DNA topoisomerase, one ...

The lagging strand is synthesized in a series of fragments, each initiated by primase, which inserts short sequences of RNA primers that will be elongated by pol III. The RNA primers are removed by another DNA polymerase, pol I, and the breaks in the sugar-phosphate backbone are sealed ...
Note that once nicks are added to the sugar-phosphate backbone, one cannot run PCR reactions on the oligos directly. To randomly access an image, a certain amount of DNA from the oPools has to be isolated, sealed using the T4 ligase and then amplified via PCR. Consequently, metadata is ...

In this DNA mimic, the negatively charged sugar-phosphate backbone of DNA is replaced by a neutral polyamide backbone composed of N-(2-aminoethyl) glycine units (Figure 1) [25]. Because of PNA chemical configuration, the nucleobases are practically positioned in the same place and within the ...
DNA structureDNA structure, showing the nucleotide bases cytosine (C), thymine (T), adenine (A), and guanine (G) linked to a backbone of alternating phosphate (P) and deoxyribose sugar (S) groups. Two sugar-phosphate chains are paired through hydrogen bonds between A and T and between G...
