Answer: The correct complementary DNA sequence for the given sequence is D. TAG-CAG-GGT.

DNA contains nucleotide pairs on a sugar phosphate backbone. The nucleotide pairs are connected by hydrogen bonds and each nucleotide pairs with only one other nucleotide. The bases are of two types: purine and pyrimidine. The purine bases bond only to pyrimidine bases. The base pairing follows Chargaff’s rule where adenine forms a pair with thymine by two hydrogen bonds and Guanine forms a bond with cytosine with three hydrogen bonds between them.

Below should be the complete one with options:

A researcher introduces a signal produced by bacteria to eukaryotic cells that she is culturing in the laboratory. Remarkably, she notices that this signal results in an increase in eukaryotic gene expression. How is this possible?

A.This gene expression is likely independent of the presence of the prokaryotic signal.

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.

C.This signaling pathway might actually be utilized by both prokaryotes and eukaryotes.

D.This signal is likely similar in structure to ligands utilized by eukaryotic cells.

E.This prokaryotic signal likely travels directly into eukaryotic cells and acts as a transcription factor.

THE CORRECT ANSWER IS B

B.The signal is either similar in structure to a ligand used by eukaryotes, or this signaling pathway is utilized by both prokaryotes and eukaryotes.
