How can you use “third-position” in a sentence? Here are some example sentences to help you improve your vocabulary:

The four-parameter model presented above requires two parameters each for two regression lines, relating the first- and second-position GC content to the third-position GC content.
We assume for simplicity that the genome is divided into two types of site - constant and variable; that all variable sites respond identically to mutational pressure; and that all third-position sites are variable (that is, that under this initial model there is no selective consequence to silent mutations).
As is the case for many other non-coding RNA genes, their degree of conservation usually exceeds that of coding regions, due to their lack of third-position wobble.
Thus, the relationship between the first-, second- and third-position GC content emerges independently in evolutionarily separate groups.
The effect cannot be fully explained by synonymous substitutions, because codons with the same third-position base but different codon doublets respond differently.
