Homologous Recombination

Homologous Recombination

The basic reaction of homologous recombination (HR) involves two chromatids that contain DNA sequences sharing a significant stretch of identity. One of these sequences uses a strand from another as a template to synthesize DNA in an enzyme-catalyzed reaction. The final product is a novel amalgamation of the two substrates. To ensure an accurate recombination of sequences, HR is restricted to the S and G2 phases of the cell cycle. At these stages, the DNA has been replicated already and the...

RNA-seq

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while...

Background:

DNA storage systems leverage biological molecules for data encoding.
Error-correcting and constrained codes are advancing DNA data storage.
Raw sequencing data processing remains a bottleneck for DNA storage efficiency.

Purpose of the Study:

To introduce RepairNatrix, a novel read-processing workflow for DNA storage.
To enhance the recoverability of encoded data by addressing errors in sequencing reads.
To enable fair and reproducible comparisons of different DNA storage approaches.

Main Methods:

Developed RepairNatrix, a workflow for preprocessing raw sequencing data.
Implemented functionality to flag and heuristically repair constraint-violating sequences.
Evaluated RepairNatrix against preprocessing strategies lacking repair capabilities.

Main Results:

RepairNatrix significantly improves the preprocessing of raw sequencing data for DNA storage.
The workflow effectively flags and repairs constraint-violating sequences, increasing data recoverability.
RepairNatrix reduced the required number of raw reads for successful, error-free decoding by 25-35x across datasets.

Conclusions:

RepairNatrix offers a tailored solution for DNA storage code processing.
The workflow enhances data integrity and reduces redundancy in DNA data storage.
RepairNatrix is publicly available on GitHub, promoting further research and development.
