چکیده
Is the code universal? No. Although most organisms have the same genetic code, researchers began to discover exceptions to the ‘universal’ code in 1979, and today we know of more than 15 alternative codes; each has just a few differences from the standard code, indicating common ancestry from this code. Several of these codes arose independently a number of times in evolution and are present in a variety of taxa.

متن کاملAssessment of genetic diversity in Pythium aphanidermatum isolates using ISSR and rep-CR methods
Sixty isolates of Pythium aphanidermatum as the causal agent of sugar beet root rot were selected on the basis of their geographical origins, morphological and genetic diversity studies. Pathogenicity test using the Kruskal-Wallis analysis showed significant differences between the pathogenic potential of isolates. Based on the growth rate, isolates were categorized in two groups with low and h...

After wheat, rice is the second most important cereal grown in Iran that improvement of its economical characteristics always has important role in the rice breeding programs. In order to estimate the genetic parameters and identify salt-tolerant varieties and hybrids in seedling stage, seven female parents (Shah-pasand, Gharib, Tarom Mahalli, Ahlami Tarom, Hashemi and Dom Sepid) and four male ...
متن کاملEfficiency of anchored and non-anchored ISSR markers to estimate genetic diversity among bread wheat cultivars
DNA markers are integrally connected to the success of molecular breeding and are fundamentally required by breeders to be able to, a. identify new gene sources in the available biodiversity, b. select parents in order to increase heterosis, c. decrease the number of backcross generations for gene introgression breeding programs, and d. carry out marker-assisted selection (MAS). The present re...
متن کاملOptimization of GRI-mech 3.0 Mechanism using HCCI Combustion Models and Genetic Algorithm
This paper presents a modeling study of a CNG Homogenous Charge Compression Ignition (HCCI) engine using single-zone and multi-zone combustion models. Authors' developed code could be able to predict engine combustion and performance parameters in closed part of the engine cycle. As detailed chemical kinetics is necessary to investigate combustion process in HCCI engines, therefore, GRI-m...

Optimisation of stacking sequence for composite plates under slamming impact loads using genetic algorithm method is studied in this paper. For this purpose, slamming load is assumed to have a uniform distribution with a triangular-pulse type of intensity function. In order to perform optimisation based on the genetic algorithm method, a special code is written in MATLAB software environment. T...
