DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the ...

Exposure to organophosphate esters (OPEs)—chemicals found in everyday ... to 10 years who were exposed to higher levels of ...

Acid phosphatase hydrolyses phosphate ester bonds under an optimum pH of 4.8 and an optimum temperature of 37 °C. In this experiment you will use an artificial substrate, para-nitrophenylphosphate ...

The structure involves three intertwined helical polynucleotide chains. Each chain, which is formed by phosphate di-ester groups and linking β-D-ribofuranose or β-D-deoxyribofuranose residues ...
