An Alternative Cracking of The Genetic Code

چکیده
We propose 22 ‘unique’ solutions to the Genetic code: an alternative cracking, from the perspective of a Mathematician. INTRODUCTION The Genetic code is now known to consist of triplet bases specifying for an amino acid (1). But before any biochemical appreciation of the genetic code, a page copy of DNA of any kind ordinarily looks like a cryptographic code – a discrete set of symbols produced by a stochastic process, which in this case are rows or lines of ten symbols: the purine and pyrimidine bases Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). In Communication theory a Secrecy system is defined as not one, but a set of many transformations of a language (2). After the key is chosen only one of these transformations is used and one might be led from this to define a secrecy system as a s ingle transformation on a language (2). In this paper, 22 ‘unique’ solutions to the Genetic code are proposed, corresponding to enciphering with 22 different keys. DNA employed for this crypto-analytical attack is Bacteriophage T4 Genome (3) (168,900’ – 137,280’) in the 5’ to 3’ direction. The Genome was obtained from GenBank with Accession number AF158101. KEYS 1. COMBINATION OF BASES AS KEY. The DNA bases form number combinations with relative frequencies. The frequencies of English letters appearing in a page of a book (4) is recorded. Assuming our code is producing English text, we set up a simple substitution (2). Using the “Probable Word” method (2), we make out several words and phrases from the DNA cryptogram.

Multi-objective Genetic Optimization of Ethane Thermal Cracking Reactor
An industrial ethane thermal cracking reactor was modeled assuming a molecular mechanism for the reaction kinetics coupled with material, energy, and momentum balances of the reactant-product flow along the reactor. To carry out the multi-objective optimization for two objectives such as conversion and ethylene selectivity, the elitist non-dominated sorting genetic algorithm was used. The Paret...
متن کاملA Pilot Study of Syngas Production from Bio-oil Thermal Cracking in a Bubbling Fluidized Bed Reactor
A fluidized bed reactor that is operating in the bubbling regime has been developed for the conversion of bio-oils to syngas.The reactor consists of a 7.6 cm I.D. (or internal diameter) bed, with an expanded freeboard. The volume of the reactor can be adjusted to vary the gas residence time. This reactor has been used to carry out either thermal or catalytic cracking for reforming bio-oils.A ga...
متن کاملAn Investigation on Corrosion and Stress Corrosion Cracking initiation of a Ferritic Stainless Steel in a Tertiary Amine Solution
The present study focused on stress corrosion cracking (SCC) and corrosion behavior of ferritic stainless steel (grade 430) in activated methyl diethanolamine (aMDEA) solution, which is classified as a tertiary amine. In this regard, cyclic polarization and U-bend tests were performed in CO2 loaded aMDEA with different concentrations at 25 and 70 °C to observe corrosion behavior and ...
متن کاملSensitivity Analysis of Stress and Cracking in Rock Mass Blasting using Numerical Modelling
Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...
