The process of DNA replication is highly conserved throughout evolution. Investigating the replication machinery in simple organisms has helped tremendously to understand how the process works in ...

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 the process — including ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

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 ...

This process is essential for the proper functioning and survival of all living organisms. DNA replication is the process by which the DNA molecule makes an exact copy of itself during cell division.

Replication of DNA DNA replication is the process by which a cell makes an identical copy of its DNA. Gene expression Only a fraction of the genes possessed by any particular cell will be expressed.

In DNA replication, the "leading" strand forges ... But the new study shows that the process is much more erratic, and strands operate more autonomously than thought. Replication can stop ...

Mitochondrial deoxyribonucleic acid (mtDNA) is essential for cellular energy production and overall cell function.

Resulting gaps are filled in by DNA polymerases; this reaction leaves a nick at or flanking the site of repair. An analogous process occurs during chromosomal DNA replication, whereby the 5’-RNA ...

If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell ... Protein synthesis isn't a slow process, either.

Molecular biologist Dirk Remus studies how cells normally copy their DNA to better understand how the process goes wrong in cancer. Looping out of control: R-loops in transcription-replication ...
