Summary
This summary is machine-generated.This study introduces a DNA-based system for storing and computing data, utilizing cellulose-based particles for enhanced stability and accessibility. It offers a new path for molecular information technologies.
Area Of Science
- Molecular Information Technology
- Biomolecular Engineering
- Data Storage
Background
- Modern information systems require stable data storage, read/write capabilities, and programmable execution.
- Nascent molecular information technologies need proof-of-principle demonstrations of these core functions.
- DNA offers high information density and parallel processing potential.
Purpose Of The Study
- To develop a DNA-based store-and-compute engine.
- To demonstrate stable data storage and retrieval using DNA on a novel substrate.
- To enable enzymatic computation and data manipulation with DNA.
Main Methods
- Encoding image files into DNA and adsorbing them onto porous cellulose acetate particles ('dendricolloids').
- Assessing the stability and longevity of DNA on the dendricolloid substrate through lyophilization, rehydration, and accelerated aging studies.
- Utilizing synthetic promoters for non-destructive data access via RNA transcription and subsequent nanopore sequencing and enzymatic computation.
Main Results
- The dendricolloid substrate provides high surface area and binding capacity for DNA, exceeding that of bare DNA.
- The DNA-based system demonstrated enhanced stability, withstanding over 170 lyophilization/rehydration cycles and projecting long half-lives (~6,000 years at 4°C).
- Data could be erased and replaced, and RNA transcripts were successfully sequenced and used for enzymatic computation (e.g., solving simplified chess and sudoku).
Conclusions
- A feasible DNA-based store-and-compute engine has been established.
- The developed system leverages the high information density and parallel computation of nucleic acids.
- This work advances the development of molecular information technologies by realizing key primordial capabilities.

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

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.

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.

Human DNA is almost two meters long. However, it is compressed inside a tiny nucleus measuring only a few microns in diameter. To make this degree of compaction possible, DNA is organized into several sequential levels so that it can fit into such a tiny space. The most compact form of DNA is a chromosome that can be seen under a microscope in a dividing cell.
In a chromosome, DNA is wound twice around a protein complex called a histone octamer core, which consists of 8 histone proteins. This...
Overview
Eukaryotes have large genomes compared to prokaryotes. In order to fit their genomes into a cell, eukaryotes must pack their DNA tightly inside the nucleus. To do so, DNA is wound around proteins called histones to form nucleosomes, the main unit of DNA packaging. Nucleosomes then coil into compact fibers known as chromatin.
