The<u> repressor </u>is a type of regulator protein that binds to a region of DNA in the promoter of a gene called the operator and prevents transcription from taking place.
In the field of science, a regulator protein can be described as a kind of protein that affects the transcription of a gene by having an influence on particular DNA sites. The rate of synthesis of various proteins is controlled by the regulator proteins.
A repressor is a kind of regulator protein that prevents the transcription of a particular gene. When the rate of a protein in the body has reached normal, the transcription of the protein needs to be stopped in order for more protein of that kind to be formed. The repressor binds itself to the operator region for the gene, hence stopping the transcription process until the protein is required again.

Lions have many other sources of prey so they would most likely still be alive. If we are excluding the existence of other animals, then lions would decrease in population after fourteen days (longest they can go without food).
