A protein binds a DNA sequence downstream of a promoter. This results in an increased rate of transcription of the gene. Which of the following site is likely to be attached? a. Operon b. Terminator c. Activator binding site d. Promotor The following are produced by algae To prepare the insert for the gene cloning, you need to find a proper source of the DNA fragment. PCR is one of the most common ways to get the gene that you...

Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of molecule "C", protein "A" changes structure and can no longer bind to the DNA sequence, resulting in reduced transcription of CBC23. What terms describe "A" and "C" respectively? Enhancer and activator Repressor and Effector Effector and activator Activator and enhancer Polymerase and activator Activator and effector

What additional genetic experiments would you suggest to verify that this region of cloned DNA contains a functional promoter? Select the two correct answers. -Insert the sequence downstream of the coding sequence for a protein whose expression is easy to assay and then introduce that chimeric construct into cells and assay for protein expression. -Use a known, control promoter to confirm that the protein-coding sequence is correct and that the protein can be detected in the cells used. -Sequence the...
