Watson-Crick Spiral

Watson-Crick spiral

The Watson-Crick helix is ​​a deoxyribonucleic acid (DNA) structure discovered by James Watson and Francis Crick in 1953. They showed that the DNA molecule has the shape of a double helix, similar to a spiral staircase.

Each helix consists of a sugar-phosphate backbone and the bases adenine, guanine, cytosine and thymine. The bases are arranged in pairs between the helices - adenine is always connected to thymine, and guanine is always connected to cytosine. This ensures complementarity of DNA strands.

Due to its unique structure, DNA can be accurately replicated during cell division. Each chain serves as a template for the synthesis of a complementary chain. In this way, genetic information is passed on from generation to generation.

The discovery of the double helix by Watson and Crick was one of the greatest breakthroughs in biology of the 20th century. It made it possible to understand the mechanisms of storage, transmission and implementation of genetic information. For this discovery, scientists were awarded the Nobel Prize in Physiology or Medicine in 1962.

Of all the three-dimensional structures, Watson Creek is one of the most complex and intriguing. One of the main features of the Watson–Crick helical structure is its ability to form double hydrogen bonds, which makes it particularly stable in all cellular systems. As a result, stronger DNA complexes are formed, increasing the stability of genetic information. In addition, the Watson–Crick structure has an important role in the processes of DNA replication, repair and transcription.

The structure of DNA was first described by Watson and Crick in 1953. Interestingly, they made their discovery based on the idea of ​​the double helix by Siegel and Davina, who put forward this hypothesis in 1875. However, despite the fact that the basic principles of the structure of DNA were already known, until the end of the 50s of the last century there was no
