What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. Meiosis, a specialized form of cell division in most ...

The DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks into phosphodiester ...
