Codons and codes
In this paper we assemble a few ingredients that are remotely connected to each other, but governed by the rule of coding theory ([1], [12]) and formal language theory, i.e. cyclic codes and DNA codes. Our interest arose from the remark that there exist both linear and circular DNAs in higher living organisms. We state the theory of codes in a wide sense due to [1] in order to understand the ci...
متن کاملWhy 4(3) codons?
An attempt is made to answer the question posed by the title of this paper. First we show that in primitive self-replicating oligoribotide systems, selection depended from the very start on the existence of 4 kinds of ribotides, forming 2 complementary pairs. Further selection required that the condensation reactions involving the two last positions of the 3'-end of a growing oligoribotide frag...
متن کاملDNATagger, colors for codons.
DNATagger is a web-based tool for coloring and editing DNA, RNA and protein sequences and alignments. It is dedicated to the visualization of protein coding sequences and also protein sequence alignments to facilitate the comprehension of evolutionary processes in sequence analysis. The distinctive feature of DNATagger is the use of codons as informative units for coloring DNA and RNA sequences...
متن کاملRare Codons Cluster
Most amino acids are encoded by more than one codon. These synonymous codons are not used with equal frequency: in every organism, some codons are used more commonly, while others are more rare. Though the encoded protein sequence is identical, selective pressures favor more common codons for enhanced translation speed and fidelity. However, rare codons persist, presumably due to neutral drift....
متن کاملAnalysis of Tourism Ethics Indicators and Codes
Background: Modern tourism has caused social, economic and environmental damage, in spite of its positive effects, in order to earn money and profit. One of the reasons for these problems is the lack of respect for ethical issues by tourists. The purpose of this article is to investigate and analyze the indicators and codes of ethical tourism from the viewpoint of tourists in the Ganjnameh tour...
