<p>A phylogenetic tree or evolutionary tree is a branching diagram or "tree" showing the inferred evolutionary relationships among various biological species or other entities—their phylogeny—based upon similarities and differences in their physical or genetic characteristics.</p>

<h2>Query</h2>
<p> A query is a form of questioning, in a line of inquiry</p>

<h1>R</h1>
<h2>Replicating Replication fork</h2>
<p>An Y shaped structure that forms within the nucleus during DNA replication. It is created by helicases, which break the hydrogen bonds holding the two DNA strands together.</p>
<p> </p>
<h2>Sequence assembly</h2>
<p>It refers to aligning and merging fragments from a longer DNA sequence in order to reconstruct the original sequence.</p>
<p> </p>
<h2>Sequencing</h2>
<p>The process of determining the nucloetide order of a given DNA fragment.</p>
<p> </p>
<h2>Topology</h2>
<p>Topology is concerned with the properties of space that are preserved under continuous deformations, such as stretching, crumpling and bending, but not tearing or gluing.</p>
<h2>Taxa</h2>
<p>It is a plural of taxon. Taxon is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit.</p>
<p> </p>
<h2>Variation</h2>
<p>Genetic variation means that biological systems – individuals and populations – are different over space.</p> <p>Each gene pool includes various alleles of genes. The variation occurs both within and among populations, supported by individual carriers of the variant genes.</p>
