Among 16843 transition-generated CGs, there were 322 (1.9%) with iHs < -2, which is not significantly different from the fraction of transition-generated Cs/Gs in the control data with iHs < -2 (2.1%, P = 0.1462, Fisher's Exact test).
There are 26391 mutations generating new CGs from other dinucleotides, of which 74% are transitions (derived from CA/TG), which is significantly larger than the fraction of transitions at control positions (64%, P < 2.2e-16, Fisher Exacteststest
A total of 9293 mutations are from CG to other dinucleotides, among which 91% are to CA/TG, which is significantly larger than the fraction of transitions for the control data (62%, P < 2.2e-16, Fisher Exacteststest
As shown in Table 1, nucleotide differences (P = fraction of transitions and Q = fraction of transversions) were used to calibrate Kimura's two-parameter model with the assumption that they began to accumulate T million years ago at the times of species divergence [ 41].
A quick extraction with EDTA probes the structural location of Cd2+, Cu2+, Pb2+, and Zn2+, and provides information on the fraction of the transition metal ions that are loosely associated with the external surfaces of the clay mineral.
The difference between 1 and the sum of switch and survival probability (Fig. 6C) provides the fraction of unidentifiable transitions through a blanking period.
Similar to the transition probabilities above, only a small fraction of the possible transitions are allowed: states where the second nucleotides in the two alleles are A and G, for example, can only transition to states where the first nucleotides are A and G, and the transition probabilities in such cases are based on nucleotide frequencies.
As indicated in Table 1, the fraction of methylation-related transitions at CpG dinucleotides was much higher outside of CpG islands than within CpG islands.
To generalize these findings to the entire class of rules for one-dimensional CA, Langton introduced a parameter, λ, that applies to each φ: for k = 2, r = 1 (binary-state, unary-range) CA, λ can be computed simply as the fraction of entries of the transition rule table that are mapped to a non-zero output (see Langton 1990, p. 14 for the general definition).
A fraction of molecules appeared to transition into an ill-defined, non-activatable "lost state", from which they recovered very slowly.
The Eyring pre-exponential term, A (s 1), contains the dimensionless transmission coefficient, κ, which represents the fraction of molecules achieving the transition state that subsequently proceed to products.
