Summary
This study designs DNA primers for stable addressing in DNA data storage. The methods ensure minimal cross-correlation for reliable random access, advancing DNA storage technology.
Area of Science:
- Bioinformatics
- Synthetic Biology
- Information Science
Background:
- Artificial DNA-based storage systems require stable address sequences for random access.
- Minimal cross-correlation and address independence are crucial for system functionality.
Purpose of the Study:
- To design DNA primers suitable for use as addresses in DNA data storage systems.
- To develop methods for constructing balanced and stable address sequences with low cross-correlation.
Main Methods:
- Extending secondary structure-avoiding DNA codes.
- Developing three distinct primer construction methods.
- Analyzing primer performance under various error channels (insertion, deletion, substitution).
Main Results:
- Generated a set of 13^8 primer sequences of length 64 with mutual uncorrelatedness.
- Developed alternative constructions yielding a higher number of weakly uncorrelated primer sequences.
- Demonstrated primer stability and functionality through simulations under error channels.
Conclusions:
- The proposed primer construction methods effectively address the need for stable and independent addressing in DNA data storage.
- The developed DNA codes and primers offer a viable solution for enabling random access in artificial DNA storage systems.
- Further research directions include optimizing primer design and exploring applications in robust data retrieval.

Overview
03:00Next-generation Sequencing
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.

01:24DNA Isolation
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...
02:40DNA Replication
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied. After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

03:01The Replisome
DNA replication is carried out by a large complex of proteins that act in a coordinated matter to achieve high-fidelity DNA replication. Together this complex is known as the DNA replication machinery or the replisome.
The synthesis of the leading and lagging strands is a highly coordinated process. To explain this, the “Trombone model” was proposed by Bruce Alberts in 1980. The DNA loop formation starts when a primer is synthesized on the parent lagging strand. The loop grows with the...

01:57Sanger Sequencing
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...
