Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases. (Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base ...

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 ...

The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe, 1999).

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 ...

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.

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 ...

Each contains one side of the original DNA and one side made of "new" nucleotides. It is possible that mistakes were made along the way -- in other words, that a base pair in one DNA molecule ...

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

The central part of each nucleosome (core particle) is a cylindrical structure (5.7 nanometers in height and 11 in diameter) ...

Yang's innovation involves a pair of DNA molecules designed to replicate this catch bond behavior. Dubbed the "fish hook" for ...

They're still the ones responsible for sorting base pairs and making sure ... But, it's water that holding the DNA helixes together. In fact, the entire helical structure of the DNA might be ...

In a first-of-its-kind breakthrough, a team of researchers has developed an artificial adhesion system that closely mimics natural biological interactions. Their research focuses on understanding how ...
