In early embryogenesis, DNA is largely devoid of methylation (top left). Post implantation, de novo methylation begins (red circles), mediated primarily by DNA (cytosine-5-)-methyltransferase-3alpha ...
First, both coding and noncoding regions of DNA are transcribed into mRNA. Some regions are removed (introns) during initial mRNA processing. The remaining exons are then spliced together, and the ...
Despite being densely packed to fit into the nucleus, chromosomes storing our genetic information are always in motion. This allows specific regions to come into contact and thereby activate a gene. A ...
Scientists are using advanced DNA sequencing technologies to uncover the secrets of our world. By performing high throughput sequencing on environmental DNA (eDNA) isolated from the soil, ice, and ...
DAYTONA BEACH, Fla. — NASCAR and the National Science Teaching Association (NSTA) today announced the launch of a new science and STEM learning curriculum for K-8 science teachers across the United ...
Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes, reducing ...
