Sentence examples for evolution of a sequence from inspiring English sources

We simulated the evolution of a sequence of 104 amino acid sites, following the tree depicted in Figure 5.

Positive selection is a measure of the amount of change in the amino acid sequence and reflects the rate of evolution of a sequence.

Failure of a model to account for major biological forces shaping the evolution of a sequence may lead to various systematic biases, such as the well-known Long Branch Attraction (LBA) artifact.

For simplicity we consider evolution of a protein sequence under purifying selection, i.e., any change in its sequence during the evolution would be deleterious; thus π0 remains unchanged throughout the simulation.

Our alignment model is expressed as a pairwise HMM transducer [ 29, 30], a conditionally normalized HMM representing the evolution of an ancestral sequence into a descendent sequence, and is similar to the transducer model in [ 20].

A wide range of factors may affect the rate of evolution of a protein sequence [ 40].

It could be due to a phase of positive selection on a new function, or to neutral evolution of a functionless sequence.

To characterize the evolution of a species, sequence analyses as well as rare genomic changes, for example, retroposon insertions, should be used (Rokas and Holland 2000).

Given the quartet tree in Figure 7, the evolution of a DNA sequence of length 10,000 with 25%-proportion of each nucleotide was simulated by Seq-Gen from the root to the four leaves u, v, x and y.

In DLH, which derive from brucite, anions of interest in the context of molecular evolution have a sequence of binding energies Cl− < < < < linear oligophosphates (like PPPi

However, sequences can slide through structures during evolution and fit of a sequence to a structure assayed with a force field is not necessarily a statement of evolutionary history.
