DNA-only Transposons02:57

DNA-only Transposons

14.4K
DNA-only transposons are called autonomous transposons since they code for the enzyme transposase that is required for the transposition mechanism. Insertion of transposons can alter gene functions in multiple ways. They can mutate the gene, alter gene expression by introducing a novel promoter or insulator sequence, introduce new splice sites, and change the mRNA transcripts produced, or remodel chromatin structure.
The donor site from where the transposon is excised is either degraded or...

DNA Isolation01:24

DNA Isolation

38.1K
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...

DNA Agarose Gel Electrophoresis02:35

DNA Agarose Gel Electrophoresis

96.0K
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...

Area of Science:

  • Biotechnology
  • Data Storage
  • Molecular Engineering

Background:

  • Exponential data growth necessitates advanced archival solutions.
  • Existing DNA storage methods are costly due to sequential, one-time synthesis per file.
  • Need for efficient and scalable DNA data storage technologies.

Purpose of the Study:

  • To introduce a novel, cost-effective DNA movable-type storage system.
  • To overcome the limitations of traditional DNA synthesis methods for data storage.
  • To demonstrate the feasibility of a reusable DNA storage approach.

Main Methods:

  • Development of prefabricated DNA movable types (DNA-MTs) encoding data, address, and checksum.
  • Enzymatic ligation of DNA-MTs into cohesive blocks using the automated BISHENG-1 DNA-MT inkjet printer.
  • In vitro and in vivo printing, assembly, storage, and retrieval of diverse data formats.

Main Results:

  • Successfully printed, assembled, stored, and retrieved 43.7 KB of data files (text, image, audio, video).
  • Utilized only 350 unique DNA-MTs, with each reusable up to 10,000 times.
  • Achieved a cost of $122/MB, significantly outperforming existing DNA storage methods.

Conclusions:

  • The DNA movable-type storage system offers a significant cost and efficiency advantage over conventional methods.
  • This reusable DNA-MT approach circumvents the need for de novo synthesis of entire DNA sequences.
  • The system demonstrates substantial potential for advancing robust DNA storage solutions for the big-data era.
