The most important gift your mother and father ever gave you was the two sets of three billion letters of DNA that make up your genome. 你父母给你的最重要的礼物就是2组包含30亿个碱基的DNA,它们构成了你的基因组。 But like anything w
DNA is an organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding o

In any organism in nature, genomic DNA is composed of two strands which in turn are composed of four deoxynucleotides bridged by a phosphodiesteric bond between the 5′-phosphate and the 3′-oxygen of two adjacent ribose moieties. From: Reference Module in Biomedical Sciences, 2017 ...
New storage technologies are needed to keep up with the global demands of data generation. DNA is an ideal storage medium due to its stability, information density and ease-of-readout with advanced sequencing techniques. However, progress in writing DNA
DNA：Structure DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what ...
Their prominence is marked by various cancers and genetic disorders that are linked to helicase defects. Although considerable effort has been made to understand the functions of DNA helicases that are important for genomic stability and cellular homeostasis, the complexity of the DNA damage response ...
THEY may not win any art prizes but these remarkable shapes are a thousand times smaller than the width of a human hair - and made out of DNA.Daily Record (Glasgow, Scotland)
Because DNA occurs in nature as long, flexible polymeric chains, it is common to find topological modifications in natural DNA strands. Indeed, circular DNAs (a simple topological modification) are probably more common than linear ones; the genomes of bacteria and of many viruses are circular,1...
How DNA Computers Will Work By: Kevin Bonsor Even as you read this article, computer chip manufacturers are furiously racing to make the next microprocessor that will topple speed records. Sooner or later, though, this competition is bound to hit a wall. Microprocessors made of silicon will ev...
