kansuensis) was 5 substitutions, 3 of which were transversions
(Kuwayama and Ozawa 2000).
In species with high divergence, the transversion
rate increases and erases the record of transitions (Brown et al.
Table 1 lists the base frequencies by base position, transition/ transversion
ratios and number of variable sites at each position.
The fingerprints of UVA involve transversion
of A:T base pairs into C:G base pairs.
All polymorphic sites were transition mutations, but there was no transversion
Activated c-Ha-ras oncogene with a guanine to thymine transversion
at the twelfth codon in a human stomach cancer cell line.
The difference between these two alleles lies in a single G[right arrow]C transversion
mutation of nucleotide 177 in ALAD2; the allozyme resulting from the ALAD2 allele contains the substitution of a neutral asparagine for a positively charged lysine at residue 59 (Wetmur et al.

ratio estimated in the jModelTest analyses.
90%) being a thymine to adenine transversion

Lillehoj (1991) indicated that the activated AFB1 metabolite, AFB1-8,9 epoxide forms a covalent bond with the N7 guanine and forms AFB1-N7 guanine adducts in target cells leading to G-T transversion
, DNA repair, lesions, mutation and tumor formation (Foster et al.
The wild-type has been designated as TPMT*1, the 3 alleles tested include TPMT*2 allele that contains a single transversion
at 238 G>C, TPMT*3A allele that contains two nucleotide transition polymorphisms 460 G>A and 719 A>G, and TPMT*3C allele that contains only a single transition polymorphism 719 A>G.

of the C for a G, leading to a TAG stop codon.
