When this DNA is collected and purified, the result is a whitish, sticky substance that is somewhat translucent. To actually visualize the double-helical structure of DNA, researchers require ...
double-helical model for the structure of DNA. Watson and Crick's discovery was also made possible by recent advances in model building, or the assembly of possible three-dimensional structures ...
Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.
James Watson (left) and Francis Crick (right) report in Nature the discovery of the double-helix structure of the DNA molecule. Papers from Rosalind Franklin and Maurice Wilkins, which appear ...
The scientists analyzed the structure of the connector – the core of the phi29 DNA packaging motor ... and the connector as a ball-race. The helical nature of the DNA converts the rotary action of the ...
She suspected that all DNA was helical but did not want to announce ... This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.
Researchers have uncovered a way to manipulate DNA at the atomic level using electric field gradients to control nitrogen ...
the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...
DNA (deoxyribonucleic acid), the molecular "blueprint" carrying the genetic instructions that influence the growth, ...
DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...
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 ...
But, it's water that holding the DNA helixes together. In fact, the entire helical structure of the DNA might be because of its hydrophobic interior in an environment that consists mainly of water.
