A complete analysis of Relative Synonymous Codon Usage in HVRs1-4 region in adenovirus genome

Abstract:
Recent outbreaks of adenovirus (FAdV) infections in poultry flocks have been determined in many countries in Europe, Asia and Australia connected with economic consequences, and loses in poultry production. To better understand the evolution and transmission of FAdV viruses, de- tailed codon usage analysis was performed for 137 recently obtained FAdV strains. A high effec- tive number of codons, and an indication the presence of low codon usage were determined. The presence of mutations, and their influence on codon usage was confirmed by a correlation be- tween nucleotide compositions at the 3rd codon positions, HVRs1-4, and ENCs. This presence indicate some influence of natural selection, and antigenic properties of examined FAdV strains.

Relative Motion Analysis - Velocity
When an external force is exerted, it sets the crank into a rotational movement. This, in turn, instigates the motion of the connecting rod, leading to what is referred to as a general plane motion. This process involves two key points - point A on the connecting rod...

Relative Motion Analysis using Rotating Axes
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...
