Answer:
The correct answer is option d. "A region of DNA sequence upstream of a gene where transcription factors bind".
Explanation:
Cis-regulatory elements (CREs) are fragments of DNA that do not encode to a protein, but regulate the transcription of nearby genes. CREs regulation is based on binding to transcription factors. These elements are vital for the regulation of complex molecular mechanisms that involve the participation of multiple genes. Additionally, CREs could participate in pleiotropy (a single gene being responsible for the development of multiple traits), because a single transcription factor could bind to different CREs.
Answer:
By using detection antibodies specific for the infected carrier
Explanation:
The enzyme-linked immunosorbent assay (ELISA) assay is widely used in molecular biology (and biochemistry) laboratories to detect and measure antibodies in the blood. The antibodies are specific immunoglobulin proteins produced by B lymphocytes, these molecules bind to specific antigens present in pathogenic microorganisms during adaptive (acquired) immune responses, thereby protecting the organism against infectious agents. In consequence, the ELISA assay is a diagnostic method to assess the immune system responses against pathogenic microorganisms. The ELISA technique is specific because it is possible to use different detection antibodies, which bind to specific antigens in the polystyrene microtiter plate.
