The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

DNA replication is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

Loss of an enzyme necessary for a process called lipoylation disrupts the way cancer cells copy their DNA, increasing their ...

He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s helical structure. By Delthia Ricks Franklin W. Stahl, a molecular biologist ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

Franklin W. Stahl, an American molecular biologist whose landmark 1957-1958 experiment with colleague Matthew Meselson revealed how DNA replicates, helping pave the way for a revolution in genetics ...

A team of researchers at VCU Massey Comprehensive Cancer Center has identified a new pathway through which mutations in the tumor suppressor p53 gene—found very frequently in human tumors—hijack DNA ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps ...
