This base-to-base bonding is not random; rather, each A in one strand always pairs with ... ladder-like structure described above, another key characteristic of double-stranded DNA is its unique ...

Crick had just learned of Chargaff's findings about base pairs in the summer ... This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

The original model of DNA structure created by Crick and Watson ... The two threads are held together by bonds between base pairs. There are four types of base - adenine, thymine, cytosine and ...

Cytosine (C) will "pair" to guanine (G), and adenine (A) will "pair" to thymine (T). How the bases are arranged in the DNA is what determines the genetic code. When the enzyme has passed the end ...

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 ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

MSK researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer.

to 10 base pairs per protein), many possibilities for DNA condensation may exist (data not shown) Interestingly, the bacterial HU protein has a different way of forming chomatin structure.
