Changes

<p>Active Site :&nbsp;The specific portion of an enzyme that attaches to the substrate by means of weak chemical bonds.</p>

<p>BLAST :&nbsp;</p>

<p>Central dogma :&nbsp;</p>

<p>Domain :&nbsp;</p>

<p>Evolution :&nbsp;&nbsp;the sequence of events involved in the evolutionary development of a species or taxonomic group of organisms</p>

<p>Allele frequency(gene frequency)<strong> : </strong>the relative frequency of an allele&nbsp;(variant of a gene) at a particular locus&nbsp;in a population,&nbsp;expressed as a fraction or percentage.</p>

<p>Gene Regulation :&nbsp;regulation of transcription; controlled by an operon which varies the accessibility of the RNA polymerase to genes being transcribed</p>

<p>Homolog :&nbsp;In biology, homology&nbsp;is the existence of shared ancestry between a pair of structures, or genes, in different taxa</p>

<p>Taxa :&nbsp;In&nbsp;biology, a&nbsp;taxon&nbsp;(plural&nbsp;taxa;&nbsp;back-formation&nbsp;from&nbsp;<em>taxonomy</em>) is a group of one or more populations of an organism or organisms seen by&nbsp;taxonomists&nbsp;to form a unit.</p>

<p>Ortholog :&nbsp;Orthologs are genes in different species that evolved from a common ancestral gene by speciation. Normally, orthologs retain the same function in the course of evolution.</p>

<p>Paralog : Paralogs are genes related by duplication within a genome. Orthologs retain the same function in the course of evolution, whereas paralogs evolve new functions, even if these are related to the original one.</p>
