When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor
Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.
Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.
<h3>How does transcription factors affect gene expression?</h3>
Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control

Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.
