Here is a list of examples in which unrelated proteins have similar functions with different structure. The convergent orientation of the catalytic triad in the active site of serine and cysteine proteases independently in over 20 enzyme superfamilies. [254] The use of an N-terminal threonine for proteolysis.
is used for the series, and, if it is convergent, to its sum. This convention is similar to that which is used for addition: a + b denotes the operation of adding a and b as well as the result of this addition, which is called the sum of a and b. Any series that is not convergent is said to be divergent or to diverge.
Divergent evolution or divergent selection is the accumulation of differences between closely related populations within a species, sometimes leading to speciation. Divergent evolution is typically exhibited when two populations become separated by a geographic barrier (such as in allopatric or peripatric speciation ) and experience different ...
A series is said to be convergent if the sequence consisting of its partial sums, (), is convergent; otherwise it is divergent. The sum of a convergent series is defined as the number s = lim n → ∞ s n {\textstyle s=\lim _{n\to \infty }s_{n}} .
More generally, if the series for f only converges for large x but can be analytically continued to all positive real x, then one can still define the sum of the divergent series by the limit above. A series of this type is known as a generalized Dirichlet series ; in applications to physics, this is known as the method of heat-kernel ...
After the final Divergent film’s 2016 debut, many of the franchise’s stars have gone on — or continued — to have very successful acting careers. Based on Veronica Roth’s book series of ...
Many examples of convergent evolution exist in insects in terms of developing resistance at a molecular level to toxins. One well-characterized example is the evolution of resistance to cardiotonic steroids (CTSs) via amino acid substitutions at well-defined positions of the α-subunit of Na +,K +-ATPase (ATPalpha). Variation in ATPalpha has ...
The top and bottom images produce a dent or projection depending on whether viewed with cross- () or wall- () eyed vergence. Autostereogram of a cube rotating Autostereogram An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene.
