These results indicate positive selection during HOTAIR's evolution.
The ratio of Ka/ Ks is usually used to characterize selective evolution of sequences: Ka/ Ks ratios of less than 0.25 indicate purifying selection, values of 1 suggest neutral evolution, and values greater than 1 indicate positive selection [ 24].
The ratio of Ka/Ks indicates protein evolution where the values of ω of > 1, = 1, and < 1 respectively indicate positive, neutral, and purifying selection.
Blue boxes indicate positive correlation; red boxes indicate negative correlation.
Arrows indicate positive signal; T bars indicate negative interactions.
That same-sex marriage could go from its preliminary draft of "diagnosable" to the final edit of "so what?" must indicate some positive evolution on the part of the larger human consciousness.
The selection pattern was characterized by the ratio of Ka to Ks substitution, in which Ka/Ks > 1 indicates positive selection or Darwinian adaptive evolution, Ka/Ks < 1 indicates purifying or stabilizing selection, and Ka/Ks = 1 indicates neutral evolution [ 61].
Selection pressure at 165th and 276th residues of our blaTEM-1 like, blaTEM-169 and blaTEM-190 proteins indicated positive selection pressures during natural evolution of these variants.
Purifying selection is indicated by ω <1, whereas ω =1 implies neutral evolution and ω >1 indicates positive selection [ 33].
A dN/dS (also known as Ka/Ks) ratio >1, <1 and = 1 indicates positive, negative, or purifying selection, and neutral evolution, respectively [ 32].
A Ka/Ks ratio < 1 indicates purifying selection, Ka/Ks = 1 suggests neutral evolution, and Ka/Ks > 1 indicates positive selection.
