Innere Eigenschaften von Atomkernen, codon family is often strongly over-used, especially in highly expressed genes, which often leads to a high dN/dS ratio because dS is very small. Many different codon usage indices have been proposed to measure codon usage and codon adaptation. Sense codon could be misread by release factors and st

Experimentelle Verfahren der Kernphysik,UAA and UAG are decoded by release factor 1 (RF1) and UAA and UGA by release factor 2 (RF2). Stop codon usage is strongly affected by both mutation bias and differential abundance of RF1 and RF2, and to a less extent by the abundance of tRNAs that may misread stop codons, e.g., misreading of UGA by

Innere Eigenschaften von Atomkernen, sense codons depend on codon frequencies, the difference between the two encoded amino acids, and the number of nucleotide site differences between the two codons (which could differ at 1, 2, or all 3 sites). Similarly, observed substitutions between two amino acids depend on amino acid frequencies

,Kernzerfälle – Radioaktivität,t have a criterion to choose the best tree, just as we need a criterion to choose the best alignment (the highest alignment score given the scoring scheme) or the best substitution model (the smallest information-theoretic indices). Maximum parsimony (MP) is one of the criteria for choosing the best

,Äußere Eigenschaften der Atomkerne,n model, is illustrated with both a brute-force approach and the pruning algorithm which is the most fundamental algorithm in likelihood calculation. The pruning algorithm is also a dynamic programming algorithm. The likelihood calculation is separately presented without and with a molecular clock.
