During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

The first section of the book, Cellular DNA Replication, begins with an excellent overview of genome duplication by Thomas J. Kelly and Bruce Stillman, followed by chapters on specific steps in ...

Conjugation is a form of horizontal gene transfer that allows the exchange of genetic material between two organisms or cells ...

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 ...

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 ...

This organization can be explained by weak interactions between ... for the control of gene expression, as well as for DNA replication, repair, and segregation to daughter cells.

The team initially set out to study another replication machinery protein ... but it's much more efficient to throw the motor out,” Wuite explained. Unlike cars, a cell has multiple DNA polymerase ...
