During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

Bacterial DNA viruses, such as the E. coli bacteriophages T4, T6, T7, and T3, encode their own ATP-dependent DNA ligases. ATP-dependent DNA ligases are also encoded by eukaryotic DNA viruses that ...

Because DNA replication errors or environmental agents that damage DNA can introduce mutations if not corrected, multiple cellular DNA repair mechanisms exist to remove damaged regions of ...

“It’s a different way of thinking about replication that raises new questions ... The researchers watched replicating DNA from E. coli bacteria. The first step in the process always ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure. Replication of DNA DNA replication is the process by which a cell makes an identical ...

Three students from Centreville High School in Clifton discovered a potentially harmful substance – DNA residues, or tiny ...
