They scanned this DNA for unique markers found only in Neandertals or Denisovans or modern humans, and found that the two Sima fossils shared far more alleles different nucleotides at the same address in the genome with Neandertals than Denisovans or modern humans.
The misinsertion frequency is the insertion efficiency of an incorrect nucleotide divided by the sum of the insertion efficiencies for incorporation of incorrect and correct nucleotides at the same concentration of nucleotides.
Accordingly, one could employ 'degenerate consensuses', which can use symbols denoting not only a single nucleotide, but different nucleotides at the same position, e.g. by using IUPAC codes [ 12], in which different letters denote a set of nucleotides (e.g. W = A or T, S = C or G, U = A,C, or G, N = any nucleotide and so on).
Our goal was to search for nonidentical nucleotides (i and j) where species X prefers nucleotide i at the consensus site while species Y prefers nucleotide j at the same site.
This study not only discovered the high conservation of the U-A-U-A-U base abundance pattern but also determined the exact nucleotide at the peak locations in these patterns and discovered exactly the same nucleotide locations at the same peaks among subkingdoms within the plant kingdom and within the animal kingdom (Table 3; Figure 2).
For the sites below that threshold and containing undetermined nucleotides, a "?" for a given allele was considered as identical to any determined nucleotide (A,G,T,C) at the same site for another allele.
Under HKY85, transversion changes to the same nucleotide occur at the same rate.
However, the Hd1 locus contained 6 new single-base substitutions and two new insertions, a 129 bp insertion and a 150 bp insertion in lf1132, in addition to a 36 bp insertion and a nucleotide substitution at the same position compared to Zhonghua 11 (Fig. 3A).
For calculation of dna, we corrected for multiple nucleotide substitutions at the same site.
(E ) Expansion of the region around the most frequently cleaved nucleotide position at the same scale as in (D ).
