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.

DNA as a Genetic Template

DNA as a Genetic Template

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...

Restriction Enzymes

Restriction Enzymes

Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.
The host bacteria protect their own genomic DNA from these enzymes by methylating these sites. Some...

DNA Isolation

DNA Isolation

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...

Area of Science:

Biotechnology
Cryptography
Molecular Computing

Background:

DNA-based cryptography offers theoretically unbreakable security via one-time pad (OTP) systems.
A key challenge is maintaining synchronization between encrypted data and the key due to DNA's tolerance for mismatched base pairs.

Purpose of the Study:

To develop an error-tolerance scheme for DNA-based OTP encryption.
To address the synchronization issue caused by DNA base pair mismatches.
To enhance the robustness of DNA encryption algorithms.

Main Methods:

Proposed a novel encryption algorithm implementation for DNA structures.
Incorporated a fourfold fault tolerance mechanism against base pair mismatches.
Compared the new method against ordinary DNA XOR operations.

Main Results:

The developed scheme demonstrates enhanced fault tolerance compared to standard DNA XOR encryption.
The proposed method aims to mitigate synchronization loss in DNA-based OTP systems.

Conclusions:

The error-tolerance scheme presents a promising advancement for DNA-based OTP encryption.
Further research is needed for practical implementation.
Molecular computation using DNA tiles could expand OTP cryptosystem applications.
