You Attempt Deletion Mapping of a Part of the Promoter

question 98

Multiple Choice

You attempt deletion mapping of a part of the promoter region of a particular gene. \ You remove a short sequence of nucleotides. Once the altered DNA is transfected into cells, the cells are able to transcribe the transfected DNA in a normal fashion. What do you conclude?

• A)The sequence that was removed is an essential part of the promoter.
• B)The sequence that was deleted is an important determinant of the ability to transcribe the gene.
• C)The sequence that was removed is not an essential part of the promoter.
• D)The deleted sequence has a moderate level of importance in promoting transcription.
• E)The deleted sequence binds tightly to RNA polymerase.
