“These bases are adenine, cytosine, guanine and thymine and can be represented as A, C, G, and T, respectively.”

“We modeled the modified complex by replacing the guanine in the native structure with coumarin and allowing rotation about the glycosidic bond.”

“All three enzymes showed a marked preference for adenine over guanine nucleotides.”

“However, experience with guanidine and biguanides prompted the development of metformin.”

“When guanidine hydrochloride is present these complexes dissociate into smaller units.”

“Urea or 6 M guanidine aqueous solutions, which are commonly used as protein modifiers, can be used as the eluent.”

“Ganciclovir is a guanosine analog that becomes strongly cytotoxic when phosphorylated.”

“Inosine is read as guanosine during translation and may alter the amino acid sequence of the encoded protein.”

“Acyclovir, an acyclic guanosine analog, binds viral DNA polymerase, acting as a chain terminator and ending replication.”

“Guanidino compounds in serum, urine, liver, kidney, and brain of man and some ureotelic animals.”

“Guanidino compounds in serum and urine of nondialyzed patients with chronic renal insufficiency.”

“Many more cave critters die in the game because of the missing guano in the food chain.”

“The copious guano deposition from sea birds may play a role in maintaining the present assemblage of vascular plants on both islands.”

“Their droppings over the centuries have coated offshore islands with guano hundreds of feet think.”
