The effect of context on synonymous codon usage in genes with low codon usage bias.
The effect of neighbouring bases on the usage of synonymous codons in genes with low codon usage bias in yeast and E. coli is examined. The codon adaptation index is employed to identify a group of genes in each organism with low codon usage bias, which are likely to be weakly expressed. A similar pattern is found in complementary sequences with respect to synonymous usage of A vs G or of U vs ...
متن کاملDi-codon usage for classification of genes
Genes are often classified into biologically related groups so that inferences on their functions can be made. This paper demonstrates that the di-codon usage is a useful feature for gene classification and gives better classification accuracy than the codon usage. Our experiments with different classifiers show that support vector machines performs better than other classifiers in classifying ...
متن کاملCodon Usage in Hemoglobin Coding Genes
Shaanxi Province, China Hemoglobin is a protein responsible for the transport of oxygen. The preference of hemoglobin coding gene is analyzed by CodonW. The relationship between the A3 / (A3 + T3) and G3 / (G3 + C3) and the relationship between GC12 and GC3 are all investigated. Finally, the preference of hemoglobin coding gene is shown and discussed. The results show that codon use preference ...
متن کاملCodon usage pattern in human SPANX genes
BACKGROUND SPANX (sperm protein coupled with the nucleus in the X chromosome) genes play a crucial role in human spermatogenesis. Codon usage bias (CUB) is a well-known phenomenon that exists in many genomes and mainly determined by mutation and selection. CUB is species specific and a unique characteristic of a genome. Analysis of compositional features and codon usage pattern of SPANX genes i...
متن کاملCorrelation matrix for quartet codon usage
It has been argued that the sum of usage probabilities for codons, belonging to quartets, that have as third nucleotide C or A, is independent of the biological species for vertebrates. The comparison between the theoretical correlation matrix derived from these sum rules and the experimentally computed matrix for 26 species shows a satisfactory agreement. The Shannon entropy, weakly depending ...
