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 ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

Since then DNA research has sought to explain the human code. Whether testing for possible diseases or tracing human history, interest in our genetic makeup has grown considerably. While we are ...

This image compares three DNA sequencing technologies: Sanger sequencing, Massively Parallel DNA sequencing, and Nanopore DNA sequencing. Sanger sequencing (left) sequences 500-700 bases per reaction ...

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 ...

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 ...

As she worked at her computer, the results revealed the sample she was examining contained human DNA. There was nothing so unusual about that in itself: at the time, the ancient DNA (aDNA ...
