DNA Isolation

DNA 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...

Overview of DNA Repair

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.
Chemically...

Base Excision Repair

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

DNA Agarose Gel Electrophoresis

DNA Agarose Gel Electrophoresis

Agarose gel electrophoresis is a laboratory technique commonly used to separate DNA fragments by size. However, it can also be used to isolate and purify DNA fragments using a gel extraction protocol.
Gel extraction follows five major steps: running gel electrophoresis to separate fragments, isolating the individual bands, extracting DNA from those bands, and removing the dye and salts from the extracted mixture to obtain pure DNA.
In cloning experiments, both the insert and vector DNA...

Background:

Current digital data storage systems have robust data recovery methods.
DNA data storage relies on inherent error correction, risking permanent data loss for uncorrectable errors.
Existing DNA data storage lacks dedicated data recovery mechanisms.

Purpose of the Study:

To develop a method for reconstructing corrupted or missing data in DNA storage systems.
To enhance the reliability and robustness of DNA-based data storage.
To provide automatic and guided data recovery solutions for DNA storage.

Main Methods:

Utilized fountain codes to exploit relationships between encoded data packets for error rectification.
Developed file type-specific and content-based data recovery strategies.
Introduced DR4DNA, a software toolkit implementing the proposed data recovery methods.

Main Results:

Demonstrated successful reconstruction of corrupted or missing DNA data using fountain codes.
Showcased the effectiveness of combining fountain code redundancy with data-specific knowledge.
Validated the DR4DNA toolkit through both in-silico and in-vitro experiments.

Conclusions:

Fountain codes offer a viable solution for data recovery in DNA storage systems.
The proposed methods significantly improve data resilience in DNA storage.
DR4DNA provides a practical tool for enhancing the reliability of DNA data storage.
