Conservative Site-specific Recombination and Phase Variation

Conservative Site-specific Recombination and Phase Variation

Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

DNA Replication

DNA 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.

DNA Microarrays

DNA Microarrays

Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

Background:

Traditional DNA data storage relies solely on nucleotide sequences.
Existing methods face challenges with error correction and metadata handling.

Purpose of the Study:

To develop a two-dimensional DNA data storage system encoding information in both sequence and backbone structure.
To enable joint data encoding, decoding, and processing for enhanced data storage.
To implement machine learning for error correction and metadata management.

Main Methods:

Developed a 2D DNA (2DDNA) method for storing images and metadata (nicks) in synthetic DNA.
Employed machine learning for automatic discoloration detection and image inpainting to mitigate errors.
Experimentally tested the platform for image reconstruction and metadata erasure/rewriting.

Main Results:

Successfully reconstructed images with minimal visual degradation.
Demonstrated permanent and privacy-preserving erasure and rewriting of copyright metadata.
Showcased robustness to degrading channel qualities without global error-correction redundancy.

Conclusions:

DNA can function as both write-once and rewritable memory for diverse data types.
The 2DDNA platform offers efficient, robust, and secure data storage solutions.
This approach advances molecular data storage capabilities for heterogeneous data.
