Genome sequencing technologies had significantly improved and scientists could gain novel insights into how DNA, which stretches a couple of meters end-to-end, is folded into a 0.002-inch-diameter cell nucleus. “The packaging of DNA in the nucleus is far from random,” says Lupiáñez. WebDNA or Deoxyribonucleic acid is the hereditary material present in all organisms. It is located within the nucleus of a cell and contains the instructions an organism needs to develop. It is a double-stranded, helical structure composed of 4 nucleotide bases, purines (Adenine and Guanine) and pyrimidines (Thymine and Cytosine). WebLong stands of double helical DNA can fit into the nucleus of a single cell because DNA is specially packaged through a series of compaction events to fit easily within cell nuclei. Even though the length of DNA per cell is about 100,000 times as long as the cell itself, it only takes up only about 10 percent of the cell’s volume. how to stay anonymous on twitter
