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 ...

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 ...

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 ...

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 ...

Later it was found that the sugar in nucleic acid can be ribose or deoxyribose, giving two forms: RNA and DNA. In 1943, American Oswald Avery proved that DNA carries genetic information.
