The genetic connections between DNA repair pathways and human cancer predisposition have fueled interest in the proteins that recognize and repair specific sites of DNA damage. The repair enzymes are ...

This keeps the DNA molecule in the form of a ribbon of consistent width. DNA stands for deoxyribonucleic acid. Nucleic acids are named for where they're found—inside the nuclei of cells—and ...

ATP-dependent RNA ligases join 3’-OH and 5’-PO 4 RNA termini via three nucleotidyl transfer steps similar to those of DNA ligases: (Step 1) ligase reacts with ATP to form a covalent ...
