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 ...

The researchers watched replicating DNA from E. coli bacteria. The first step in the process always sees the double helix “unzipping” into two strands — a “leading strand” and a ...

Trends in Genetics 22, 46–55 (2006). Argueso, J. L. et al. Double-strand breaks associated with repetitive DNA can reshape the genome. Proceedings of the Naitonal Academy of Sciences 105 ...

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 ...

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 ...

They are essential for the survival and reproduction of life on Earth. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). TComparison of a single-stranded ...

Genetically speaking, it's a bacterium's worst-case scenario: During transcription, newly minted RNA sticks to its DNA template, forming a 3-stranded ... can be disastrous, leading to DNA breaks ...
