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 ...

Accurate transmission of the genetic information requires complete duplication of the chromosomal DNA each cell division cycle. However, the idea that replication forks would form at origins of DNA ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

“It’s a different way of thinking about replication ... DNA from E. coli bacteria. The first step in the process always sees the double helix “unzipping” into two strands — a “leading ...

It interferes with DNA synthesis by incorporating into the growing DNA strand, leading to the termination of DNA replication and cell death. Some pyrimidine derivatives, such as pyrithiobac and ...

The study uncovered that salt concentration changes at the gas-water interface could drive DNA strand separation, a critical step in replication. This discovery challenges previous assumptions ...

The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, the complementary base pairing ensures faithful ... disrupt the function of chloride channels ...
