Maxam-Gilbert Sequencing

Maxam-Gilbert Sequencing

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Genomic DNA in Eukaryotes

Genomic DNA in Eukaryotes

Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.

Next-generation Sequencing

Next-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....

Background:

DNA storage presents significant advantages in capacity, stability, and energy efficiency for multimedia data.
Current limitations include low coding density and insufficient error correction capabilities.

Purpose of the Study:

To enhance the efficiency and reliability of DNA-based image storage and reconstruction.
To address the limitations of low coding density and weak error correction in DNA data storage.

Main Methods:

Development of DNA-QLC, integrating a quantized ResNet Variational Autoencoder (QRes-VAE) for image compression.
Utilization of Levenshtein coding (LC) for robust DNA sequence error correction.

Main Results:

DNA-QLC achieves a net information density 2.4 times greater than DNA Fountain.
Demonstrated high-fidelity image reconstruction (SSIM of 0.917) even at a 2% error rate.
Generated DNA sequences adhere to combinatorial constraints.

Conclusions:

The DNA-QLC encoding scheme significantly improves the efficiency and reliability of DNA storage systems.
Enhanced performance boosts the potential of DNA storage for storing multimedia information, particularly images.
