Tiny robots could serve all kinds of useful functions, but shrinking their actuators has proven challenging. Now researchers at the University of Wollongong (UOW) in Australia have made artificial ...

A team of physicists working at the intersection of theory and experiment are shedding new light on the “teamwork” of molecular motors—called RNA polymerases (RNAPs)—that mediate DNA transcription.

Supercoiling and looping can transmit mechanical stress along the DNA backbone that can promote the separation of the strands of the double helix at specific distant sites, exposing the DNA bases, ...

Although it also performs some functions in men, estrogen, the main female sex hormone, is involved in a myriad of processes, ...

A cell has many ways to regulate gene expression, one of which is the structure of the genome itself; active genes have to be accessible to the cellular machinery to be expressed. The DNA in the ...

Estrogens, the main female sex hormone, although they also perform some functions in men, are involved in a myriad of ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 86, No. 16 (Aug. 15, 1989), pp. 6121-6125 (5 pages) Incubation of topologically relaxed plasmid DNA with simian ...

Picture in your mind a traditional "landline" telephone with a coiled cord connecting the handset to the phone. The coiled telephone cord and the DNA double helix that stores the genetic material in ...
