The DNA double helix is made from two strands that run in opposite directions. Each strand is made of a series of bases, A, T, C and G, that pair up between the strands: A to T and C to G. The first ...

This shows up as a dark area in the glowing strand, because the dye doesn’t stick to single-stranded DNA. “We’ve shown that there is no coordination between synthesis of the two strands.

MMEJ is complementary to two other processes — homologous recombination and non-homologous end joining — that repair DNA double-strand breaks, but with lower fidelity because Pol theta is prone to ...

The exact moment DNA starts to unravel has been seen by scientists for the first time, exposing a chemical process that is essential for DNA to be the molecule that codes for all life.

The final DNA strand contains close to 1,700 nucleotides. When the researchers heated and cooled their DNA strands in a test tube, each one folded in on itself and snapped into a virus-size ...

This study suggests that primer synthesis does not pause DNA synthesis, and that primers are made concomitant with DNA synthesis, kept close to the replication complex by the lagging strand ...

By creating a more true-to-life representation of DNA's environment, researchers at Northwestern University have discovered that strand separation - the essential process a "resting" double helix ...

All Wound Up: A single strand of DNA forms a chromosome, like the one displayed to the left. This chromosome is magnified (1000x). That's not nearly enough to show a single strand of DNA, ...
