Transcription is the process of making an RNA copy of one of the strands of DNA. It initiates at DNA regions called promoters. In bacteria, as in other organisms, regulation of gene expression is ...

The tight wrapping of genomic DNA around nucleosomes in the cell nucleus makes it unavailable for gene expression. A team of Ludwig-Maximilians-Universitaet (LMU) in Munich now describes a mechanism ...

DNA nanotechnology has established approaches for designing programmable and precisely controlled nanoscale architectures through specific Watson—Crick base-pairing, molecular plasticity, and ...

An interview with Paul Modrich, James B. Duke Professor of Biochemistry and Chemistry at Duke University. Modrich was awarded the 2015 Nobel Prize for Chemistry jointly with Tomas Lindahl of the ...

Researchers at the University of Rochester in New York have developed a DNA computer that’s capable of performing square root calculations of numbers all the way up to 900. It’s an impressive ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 112, No. 16 (April 21, 2015), pp. 5033-5038 (6 pages) ssDNA binding proteins (SSBs) protect ssDNA from chemical ...

(Nanowerk News) Researchers are constantly expanding their arsenal of methods to decipher the spatial organization of biological structures. Using microscopes, they can now visualize individual ...

A team of researchers found that DNA damaged by the widely used chemotherapy drug cisplatin is mostly good as new in noncancerous tissue within two circadian cycles, or two days. The results could ...

A volley of criticism against a claim that a certain extremophile bacterium from arsenic-rich Mono Lake in California incorporates arsenic into its DNA backbone was published in the June 3 issue of ...

Although four DNA bases — adenine, thymine, cytosine and guanine — make up much of the genome, modified bases can serve special purposes. Trypanosomes, parasitic protozoa, contain an additional base ...
