…current research we developed a versatile “meta-DNA” (M-DNA) strategy that allowed various sub-micrometer to micrometer-sized DNA structures to self-assemble in a manner similar to how simple short DNA strands self-assemble…
…or DNA. Adding DNA to the mix Mention DNA to most people, and they think of biological functions in living things. But the members of Furst’s lab view DNA as…
…the protein Rad51 repairs DNA and fixes mutated DNA sequences, which otherwise could lead to cancer. “To understand cancer, we need to understand how DNA repairs. To understand that, we…
…bases. Here the researchers have used artificial DNA sequences instead of natural genetic DNA. In the future, they will work towards overcoming this limitation. Reference: “Folding Double-Stranded DNA into Designed…
…yield mind-boggling amounts of data that must be analyzed. Deeper dive into DNA When most people think of DNA, they think of life, not computers. But DNA is itself a…
…in a blood cell. When DNA is replicated during cell division, the epigenetic marks associated with the DNA, including DNA methylation, are diluted. The newly created DNA strands need to…
…scientists began creating tiny two-dimensional structures from DNA using a strategy called DNA origami — the construction of shapes from a DNA “scaffold” strand and smaller “staple” strands that bind…
…sites, exposing the DNA bases, which may facilitate repair, replication, transcription, or other aspects of DNA function. “DNA stores a cell’s genetic information in a stable and protected form that…
…DNA with a new DNA sequence, the researchers found. For DNA deletion and editing in the lab, scientists program CRISPR systems to target specific DNA in the genome of an…
…the history of evolution has been opened after two-million-year-old DNA has been identified for the first time. Researchers discovered microscopic fragments of environmental DNA in Ice Age sediment in northern…
…relied on DNA from bones and teeth, which store DNA and protect it from the environment. But such skeletal remains are exceedingly rare, leaving large parts of human history inaccessible…
…the geneticists in Leipzig isolated not only the DNA from the animal itself, a wapiti deer, but also large quantities of ancient human DNA. “The amount of human DNA we…
…gene expression, distinguish indigenous DNA from foreign DNA, or mark old DNA strands during replication. Methylation is carried out by certain enzymes called methyltransferases, which decorate DNA with methyl groups…
…have published a paper proving that four-stranded ‘quadruple helix’ DNA structures – known as G-quadruplexes – also exist within the human genome. They form in regions of DNA that are…
