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 ...

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are ...

Traits as diverse as the color of a person's eyes and the scent of a rose are determined by the information contained in DNA. Learn how this information is coded by strings of molecules called ...

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 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 ...

This is a preview. Log in through your library . Abstract The activation-induced cytidine deaminase (AID) is required for somatic hypermutation (SHM) and class-switch recombination of Ig genes. It has ...

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 ...

The double helix of DNA is one of the most iconic symbols in science. By imitating the structure of this complex genetic molecule we have found a way to make artificial muscle fibers far more powerful ...
