DNArakenteen
DNArakenteet, or DNA structures, refer to the physical configurations and arrangements of deoxyribonucleic acid (DNA) molecules within cells. DNA is the hereditary material in living organisms, carrying genetic instructions for development, functioning, growth, and reproduction. While the classic double-helix model is the most well-known structure, DNA can form various other configurations depending on environmental conditions, sequence composition, and interactions with proteins or other molecules.
The double-helix structure, discovered by James Watson and Francis Crick in 1953, consists of two long strands
Beyond the double helix, DNA can adopt alternative structures such as Z-DNA, where the helix twists in
DNArakenteet are also influenced by modifications such as methylation, which can alter the physical properties of
