Through the technique of DNA sequencing, first developed by Frederick Sanger, scientists can determine the exact order of nucleotides in an organism’s genes. Knowing this order is the first step ...

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 ...

As the world continues to generate data at an unprecedented rate, the search for efficient storage solutions has intensified.

The nucleotides (A, T, G, and C) on each strand pair up with free nucleotides in the nucleus, creating two new strands. But only G can pair with C, and only T can pair with A.

The DNA encoding all life on Earth is made of four building blocks called nucleotides, commonly known as 'letters,' that line up in pairs and twist into a double helix. Now, two groups ...

Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as ...

Ionizing radiation produces many types of DNA lesions that have the potential of killing cells. The lethal lesion is probably an unrepaired or misrepaired double-strand break produced as part of a ...

The difference lies not only in the sequence of the nucleotides, the "beads" that form the strand, but also in the three-dimensional structure that this long molecule takes on.
