Most people think that genetics is the most intricate branch of biology and medicine. Surely it is no different, because, as we know, genetics is also the least developed branch of biology and medicine.

It started to develop quite late and still man does not have the skills and knowledge to get to know her riddles. However, in spite of everything, we already know a lot.

What is DNA and how is it built?

So what is DNA? It is an abbreviation for “deoxyribonucleic acid” and consists of many nucleotides, in the form of two threads twisted into helix. It serves as an information carrier for organisms. The main component of this acid is a nucleotide, which contains five-pointed sugar or deoxyribose, the next element that introduces differentiation in this substance is the nitric principle and there are four types of nitrogen bases of DNA. It is adenine, thymine, cytozine and guanine. Another element is phosphate residue.

These components form one specific nucleotide, which binds to another hydrogen bond through nitrogenous bases. Of course, it should be remembered that the nitrogenous bases, which we mentioned above, combine with each other according to the principle of complementarity. This means that adenine will always bond with thymine with a double hydrogen bond, while guanine with cytosine will always bond with a triple hydrogen bond.

Please remember that there are no deviations from this rule. What is the difference between RNA and DNA? Instead of thymine, there is uracyl binding to adenine, and there is no deoxyribose, but ribose.
