Which of the following does not happen for the CREB protein to activate a gene?

Patients with Xeroderma pigmentosum are highly susceptible to (                 ), as they have a defect in (                           ).

The role of sigma factor during bacterial transcription is to cause

Which curve (A or B) is more aggressive? 

Which curve (A, B, or neither or both) is guaranteed to have a characteristic equation with complex roots? 

Researchers conducted Northern blotting on a sample of cells from mouse kidney, brain, and liver using a probe that is complementary to a gene that encodes a glucose transporter.  All of the samples were taken from the same mouse. The following results were obtained: If we assume that equal amounts of total cellular RNA was loaded into each lane, which of the following statements is true?  

Below is the problem statement for the question 16 and 17   The Process is

A primer used in dideoxy DNA sequencing is 20 nucleotides long and has the following sequence:  5’-GGATCCATGACTAGTCCGAC-3’. A segment of DNA is cloned into a vector and then the vector DNA is denatured and subjected to the dideoxy DNA sequencing method. Below is the DNA sequence from a region of the vector. The primer-annealing site is shown bold and underlined.    3-CCCGATCGGCCTAGGTACTGATCAGGCTGAATGACTCTTCAGA-5’   Based on the sequence above, what would be the size(s) of the band(s) (i.e., the number of nucleotides in each band) in which dideoxyG had been added to the sequencing reaction?

During dideoxy sequencing, dideoxynucleotides
