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 ...

Matthew Meselson and Franklin Stahl's 1957 demonstration of DNA replication is considered "the most beautiful experiment in biology ... "1 Their follow-up paper explained the probable ...

DNA replication is happening continuously throughout the body, as many as trillions of times per day. Whenever a cell divides -- whether to repair damaged tissue, replace old cells, or simply to ...
