Sentence examples for bases of a codon from inspiring English sources

Constraint analyses also showed that when forcing both the second and first bases of a codon, S values were minimal when the second base was C, particularly when the number of hydrogen bonds established by the first two base pairs was maximal (6 hydrogen bonds; codons CCN and GCN) (Figure 3B).

According to the position of the introns, these genes are divided into the following three types: phase 0 (introns between codons), phase 2 (introns between the first and the second bases of a codon) and phase 3 (introns between the second and the third bases of a codon).

Intron phase was analyzed manually based on the intron-exon border information: phase 0 designated introns between codons, phase 1 designated introns between the first and second bases of a codon, and phase 2 designated introns between the second and third bases of a codon.

The term frame position is used to denote one of the 3 possible positions 0, 1, or 2 by our convention relative to the first base of a codon.

This corresponds to the wobble base of a codon triplet that appears to correlate with enhanced RNA secondary structure at the third base of a codon.

All mutations concerned the third base of a codon, and 5/10 represented a T>C mutation.

Of the 74 intron positions, 25 are in phase zero (between two codons), 27 are in phase one (between the first et second base of a codon) and 22 are in phase two (between the second and third base of a codon).

Maximum Likelihood trees calculated in MrBayes [44] [48] were set to a DNA data type, a 4×4 nucleotide model, Nst of 6 with a Dirichlet prior, no covarion, four states with frequencies of a Dirichlet prior, an invariable gamma (default settings), vertebrate mitochondrial code and were partitioned by codon position (1st, 2nd or 3rd base of a codon).

Respectively, two and four phase 1 (after the first base of a codon) and phase 2 (after the second base of a codon) introns were identified, whereas intron positions 7 and 17 occurred in two phases (0 and 1).

The majority of the polymorphisms (four out of six) occurred in the coding sequence, and of these, three were silent changes in the third base of a codon.

It should also be noted that for both Nme3 and Nme4, the first intron is inserted after the first base of a codon.
