Position-effect Variegation

Position-effect Variegation

In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

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 Agarose Gel Electrophoresis

DNA Agarose Gel Electrophoresis

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...

Background:

Images are vital data carriers in the big data era, necessitating robust security measures.
Image encryption is a key strategy for protecting sensitive visual information.
Existing encryption methods may face challenges in complexity and security against sophisticated attacks.

Purpose of the Study:

To propose and evaluate a novel color image encryption scheme named EDPD.
To enhance the security and efficiency of image encryption using DNA-level operations and hyperchaotic systems.
To demonstrate the resilience of the proposed scheme against potential security threats.

Main Methods:

The EDPD scheme integrates Secure Hash Algorithm-512 (SHA-512), a four-dimensional hyperchaotic system, and eight-base DNA-level permutation and diffusion.
Initial values for the chaotic system are derived from plaintext images using SHA-512.
Encryption involves generating a hyperchaotic sequence, applying dynamic eight-base DNA encoding, permutation, and diffusion across multiple dimensions, followed by DNA decoding.

Main Results:

Experimental results on standard test images demonstrate the EDPD scheme's effectiveness.
The proposed method exhibits excellent performance in color image encryption.
The scheme shows strong resistance against various types of security attacks.

Conclusions:

The novel EDPD scheme offers a secure and efficient solution for color image encryption.
The integration of hyperchaotic dynamics and DNA-level operations provides a robust security framework.
The EDPD scheme is a promising approach for safeguarding image data in the big data landscape.
