It is this alternating sugar-phosphate arrangement that forms the "backbone" of a DNA molecule. Figure 3: All polynucleotides contain an alternating sugar-phosphate backbone.

The discovery of DNA structure by James Watson and Francis Crick in the year 1953 is one of the most revolutionary scientific discoveries to date. However, the research leading to the discovery of ...

The two strands of DNA form a 3-D structure called a double helix. When illustrated, DNA looks like a spiral ladder in which the base pairs are the rungs, and the sugar-phosphate backbones are the ...

B-DNA is the most common form of DNA and has a right-handed double helix structure. A-DNA forms in a shorter, right-handed double helix. The function of this form is to protect DNA.

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to ...

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. But where and how does the famous double helix fit into ...

Water molecules surround the genetic material DNA in a very specific way. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have discovered that, on the one hand, the texture of this ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

The structure of DNA made visible Date: August 31, 2015 Source: ResearchSEA Summary: From 1952, DNA was sequenced, modified and extensively studied, but no technique was able to produce clear ...

In the second step, the AMP is transferred to the 5’-end of the 5’-phosphate-terminated DNA strand to form DNA-adenylate — an inverted pyrophosphate bridge structure, AppN. In this reaction, the ...

Deficiencies in aprataxin, which reverses 5′-adenylate DNA adducts, can lead to the neurodegenerative disorder AOA1. Mutagenesis analyses and the crystal structure of the aprataxin ortholog from ...
