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.

With this approach, DNA origami nanotechnology can be used to build precise, pre-programmed 2D and 3D shapes. The biggest challenge was making the pores open and close on-demand.

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 ...

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, ...

How timely it is that Edward Ball’s new book, “The Genetic Strand: Exploring a Family History through DNA,” comes out after the recent flap over racially charged comments by famed molecular ...

CRISPR uses what is called guide RNA to get the Cas-9 enzyme to a more precise spot on the DNA strand ... An earlier version of this story misstated the number of base pairs that make up human DNA.

Close encounters between distant DNA regions cause bursts of gene activity. ScienceDaily . Retrieved June 11, 2025 from www.sciencedaily.com / releases / 2024 / 12 / 241206161918.htm ...

They engineered a modified version of Taq polymerase by linking thioredoxin to TBD and positioning the domain close to the active site, where the polymerase adds nucleotides to the growing DNA strand.
