The nitrogen bases are the rungs. Every rung is actually two types of nitrogen bases that pair together to form a complete rung and hold the long strands of nucleotides together.
Remember, there are four types of nitrogen bases, and they pair together specifically — adenine pairs with thymine, and guanine with cytosine. Human DNA is unique in that it is made up of nearly 3 billion base pairs, and about 99 percent of them are the same in every human.
Think of DNA like individual letters of the alphabet — letters combine with one another in a specific order and form to make up words, sentences, and stories. The same idea is true for DNA — how the nitrogen bases are ordered in DNA sequences forms the genes, which tell your cells how to make proteins. Ribonucleic acid RNA , another type of nucleic acid, is formed during the process of transcription when DNA is replicated. DNA is essentially a recipe for any living organism.
During this process, DNA unwinds itself so it can be replicated. RNA acts as a messenger, carrying vital genetic information in a cell from DNA through ribosomes to create proteins, which then form all living things.
DNA was discovered in by Swiss researcher Friedrich Miescher, who was originally trying to study the composition of lymphoid cells white blood cells. Instead, he isolated a new molecule he called nuclein DNA with associated proteins from a cell nucleus. While Miescher was the first to define DNA as a distinct molecule, several other researchers and scientists have contributed to our relative understanding of DNA as we know it today.
The full answer to the question who discovered DNA is complex, because in truth, many people have contributed to what we know about it. DNA was first discovered by Friedrich Miescher, but researchers and scientists continue to expound on his work to this day, as we are still learning more about its mysteries.
Watson and Crick contributed largely to our understanding of DNA in terms of genetic inheritance, but much like Miescher, long before their work, others also made great advancements in and contributions to the field. The future of DNA has great potential. DNA insights are already enabling the diagnosis and treatment of genetic diseases. Science is also hopeful that medicine will advance to be able to leverage the power of our own cells to fight disease. For example, gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a therapeutically beneficial protein.
Researchers also continue to use DNA sequencing technology to learn more about everything from combating infectious disease outbreaks to improving nutritional security.
Ultimately, DNA research will accelerate breaking the mold of the one-size-fits-all approach to medicine. Every new discovery in our understanding of DNA lends to further advancement in the idea of precision medicine, a relatively new way doctors are approaching healthcare through the use of genetic and molecular information to guide their approach to medicine.
With precision or personalized medicine, interventions take into consideration the unique biology of the patient and are tailored individually to each patient, rather than being based on the predicted response for all patients. Using genetics and a holistic view of individual genetics, lifestyle, and environment on a case-by-case basis, doctors are better able to not only predict accurate prevention strategies, but also suggest more effective treatment options.
This structure, announced in their famous paper in the April issue of Nature, explained how the DNA molecule could replicate itself during cell division, enabling organisms to reproduce themselves with amazing accuracy except for occasional mutations.
