Answer:
An Enhancer
Explanation:
Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.
According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.
Answer:
Enzymes are proteins that increase (only) the rate of chemical reactions converting substrate into product.
Catalysts are substances that increase or decrease the rate of a chemical reaction but still remain unchanged.
