The structure of DNA can also be described as a ladder. The chemical backbones of the ladder are made up of sugar and phosphate molecules that are connected by chemical bonds. The rungs of the ...

The new pairs may also be used in a SELEX (systematic evolution of ligands by exponential enrichment)-based method to expand the chemical characteristics of DNA to generate new protein-binding ...

Sheep have been part of human life for over 11,000 years. First domesticated in the western Fertile Crescent, their impact ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

DNA is made up of adenine-thymine (AT) bonds and guanine-cytosine (GC) bonds. The frequency of each type of bond differs substantially across bacterial species. A new study uses this quirk of ...

The two threads are held together by bonds between base pairs. There are four types of base - adenine, thymine, cytosine and guanine. All human cells contain DNA. The 3 billion pairs of bases in ...

Nitrogen atoms in DNA are bonded with either three or two atoms ... the principal axis either aligns with the bisector of the bonds or is close to perpendicular to it, depending on the base ...

In a first-of-its-kind breakthrough, a team of UBC Okanagan researchers has developed an artificial adhesion system that closely mimics natural biological interactions. Dr. Isaac Li and his team ...

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 ...

Cells express their genes by converting the genetic message into protein. This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed ...
