Example sentences for: codons
How can you use “codons” in a sentence? Here are some example sentences to help you improve your vocabulary:
The model outlined above requires four parameters (estimated GC1 and GC2 at GC3 = 0% and GC3 = 100%) defined from the data, and uses these to predict the slopes and intercepts of regressions on GC content of the 64 codons and 21 codon sets (20 amino acids and termination).
The strength of the selection on a given gene relative to the mutation pressure can be estimated by the method of the relative neutrality plot (RNP), which gives indications on how 'neutral' a coding sequence can be considered [ 18 19 ] . The method consists of plotting the G+C content at the constrained (or nonsynonymous) positions (that is, first and second positions) of the codons against the G+C content at the relaxed (or synonymous) position (that is, third position).
We compare the predicted and actual slopes for each of the 64 codons in Figure 5. The model explains 77% of the variance in slopes for the regression of codon frequency on GC content in eukaryotes, and 80% of the variance in prokaryotes.
This can be remedied by taking into account the differential effect of selection on the different positions within codons.
The Fitch group also identifies 6 additional codons as positively selected.
