DNA as a unit of life

Аннотация

DNA is our memory, the repository of information passed down to us by our ancestors. It was first discovered by a young and unknown doctor from Switzerland - Friedrich Miescher in 1869. Later, in 1953, the English physicist Francis Crick and the American biologist James Watson managed to build a structural model of DNA. So what is a deoxyribonucleic acid molecule? DNA is a macromolecule consisting of two spirally twisted chains that provide storage and transmission of hereditary information. It is this nucleic acid that can be said to define us, our past and our future.
