DNA as a Genetic Template02:05

DNA as a Genetic Template

24.9K
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...

Sanger Sequencing

DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Next-generation Sequencing

95.9K
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.

Maxam-Gilbert Sequencing

11.9K
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.

From DNA to Protein03:06

From DNA to Protein

21.0K
The flow of genetic information in cells from DNA to mRNA to protein is described by the central dogma, which states that genes specify the sequence of mRNAs, which in turn specify the sequence of amino acids making up all proteins. The decoding of one molecule to another is performed by specific proteins and RNAs. Because the information stored in DNA is so central to cellular function, it makes intuitive sense that the cell would make mRNA copies of this information for protein synthesis...

Area of Science:

  • Biotechnology and Synthetic Biology
  • Molecular Communications
  • Biomedical Engineering

Background:

  • DNA-based molecular communications (DMC) are essential for biological network regulation but face challenges in speed, complexity, and decoding vulnerability.
  • Existing genome-coded DMC systems are often impaired by external stimuli, limiting their effectiveness in maintaining organismic functions.

Purpose of the Study:

  • To develop an innovative DNA framework-based artificial DNA encoder for enhanced DMC.
  • To demonstrate the encoder's capability for active sensing, real-time actuation, and robust free radical decoding.
  • To investigate the encoder's potential for synergistic anti-obesity effects by modulating inflammatory networks.

Main Methods:

  • A proof-of-concept study utilizing a free-radical cascade was employed.
  • Development and implementation of a DNA framework-based artificial DNA encoder.
  • Evaluation of the encoder's sensing, decoding efficacy, and resistance to environmental noise.

Main Results:

  • The artificial DNA encoder demonstrated active sensing and real-time actuation capabilities.
  • The system achieved broad, in situ free radical-decoding efficacy with robust resistance to environmental noise.
  • The encoder successfully blocked communication between free radicals and inflammatory networks, yielding a synergistic anti-obesity effect.

Conclusions:

  • The developed artificial DNA encoder represents a significant advancement in DNA-based molecular communications.
  • This novel DMC strategy offers improved reliability, noise resistance, and therapeutic potential, exemplified by its anti-obesity effects.
  • The artificial DNA encoder-based DMC approach is potentially generalizable to diverse communication systems and applications.
