More than 4,000 years ago, Egypt and Mesopotamia stood as two of the most complex societies on the planet. But the new DNA ...

Scientists have for the first time sequenced the most complete and oldest ancient Egyptian genome ever found—unlocking new ...

Artificial human DNA, or synthetic DNA (synDNA), would be made without biological parents by instead using chemicals. SynHG ...

“PDI is like a double agent,” Dr Shadfar explains. “In healthy cells, it repairs DNA and helps prevent disease. But in cancer, it gets hijacked — it ends up protecting the tumour instead of the body.

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break invol ...

At some point, RNA must have replicated itself before the evolutionary arrival of DNA and proteins, and now we might know how.

These physical spacers are known as L2 loops, and each insertion exposes the bases of three DNA nucleotides that are then available for the invading strand to pair to, probing for homology.

“The structure reveals for the first time the mechanism underlying the strand exchange process during DNA repair via homologous recombination.” Joudeh served as co-lead author of the study alongside ...

Measurement of the conformation of DNA in protein–DNA complexes is important to decipher the role of the DNA conformation and dynamics in protein recognition and function. In this work, we report a ...

Schematics, AFM images at low magnification (upper) and high magnification (lower), and cross-sectional (upper) and axial (lower) height profiles of functionalized DNA origami nanotubes with 9 biotin ...
