According to the published information, eukaryotic DNA transposons identified so far in eukaryotes belong to three classes characterized by the so-called cut-and-paste, rolling-circle and self ...

For example, DNA is stored, replicated and processed in the eukaryotic cell's nucleus, which is itself surrounded by a selectively permeable membrane. This protects the DNA and allows the cell to ...

Genetic material DNA in a nucleus, plasmids are found in a few simple eukaryotic organisms. DNA is a single molecule, found free in the cytoplasm; additional DNA is found on one or more rings ...

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 ...

In the third step, ligase catalyzes attack by the 3’-OH of the nick on DNA-adenylate to join the 2 polynucleotides and liberate AMP. ATP-dependent DNA ligases are found in all eukaryotic species.

offering new clues about the relationship between these microbes and the rise of early eukaryotic cells, many researchers tell The Scientist it’s entirely possible that some questions will never be ...

Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.

Transposons, or "jumping genes" - DNA segments that can move from one part of the genome to another - are key to bacterial evolution and the ...

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