This means that one strand's sugar-phosphate chain runs in the 5' to ... were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

DNA is negatively charged, due to the phosphate groups in its phosphate ... fiber may be highly irregular and not quite the uniform structure depicted in instructive drawings such as Figure ...

In the second step, the AMP is transferred to the 5’-end of the 5’-phosphate-terminated DNA strand to form DNA-adenylate — an inverted pyrophosphate bridge structure, AppN. In this reaction, the ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
