DNA is composed of four types of nucleotides, or bases, each designated by a letter: adenine (A), thymine (T), guanine (G), and cytosine (C) – or CGAT for short. These bases intertwine in a spiral ...

The building blocks of DNA have been found in samples returned to Earth from an asteroid, suggesting life rained down from ...

During ssDNA translocation of PcrA and UvrD monomers, the hydrolysis of one molecule of ATP is coupled to movement by one base along the DNA. However, in many cases, larger translocation steps of ...

There are four types of base - adenine, thymine, cytosine and guanine. All human cells contain DNA. The 3 billion pairs of bases in each cell fit into a space that is six microns across.

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

A recent study by researchers from Peking University demonstrates the potential of nuclear electric resonance to control the nuclear spins of nitrogen atoms in DNA using electric field gradients, ...

Asteroids, small airless bodies within the inner solar system, are theorized to have contributed water and chemical building ...

Samples contain all five nucleobases of DNA and RNA, supporting theory that asteroids may have seeded Earth with life's ...

"The length and structure of a single DNA molecule, its specific base sequence, and its interactions with proteins must be observed by stretching it for detailed analysis." Azuma and his ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
