When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

Scientists have found that non-coding 'junk' DNA, far from being harmless and inert, could potentially contribute to the development of cancer. Their study has shown how non-coding DNA can get in the ...

In a new study, stem cell scientists at the Lund University, Sweden, explore the role of non-coding regions of the genome—previously deemed to be functionless “junk” DNA—and find humans and ...

Butterfly wing patterns have a basic plan to them, which is manipulated by non-coding regulatory DNA to create the diversity of wings seen in different species, according to new research. The study, ...
