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 ...

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 ...

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 ...

Due to DNA’s chemical structure, helicases can only move in one direction along a single strand. By binding at two points simultaneously, they enable unwinding in both directions, achieving a ...

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 ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen ... Peptide bonds form between the adjacent amino acids to finalise the structure.
