The dark bands indicate areas where the structure of the chromosome is dense ... We've now zoomed in enough to see portions of the DNA strand. The DNA is wrapped around histones -- protein ...

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule. Free DNA nucleotides – needed to form the new ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The double helix unwinds, and each strand serves as a ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

In the double helix structure of DNA, thymine forms a base pair with adenine ... DNA polymerase enzymes use the existing DNA strand as a template and add the complementary nucleotides, including ...
