DNA function & structure (with diagram) (article) Khan Academy
DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical … 더 보기 Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and 더 보기 Base modifications and DNA packaging The expression of genes is influenced by how the DNA is packaged in chromosomes, in a structure called chromatin. … 더 보기 DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. The set of chromosomes in a cell makes up its genome; … 더 보기 A DNA helix usually does not interact with other segments of DNA, and in human cells, the different chromosomes even occupy separate areas in the nucleus called "chromosome territories". This physical separation of different chromosomes is … 더 보기 DNA is a long polymer made from repeating units called nucleotides. The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes. In all species it is composed of two helical chains, bound to each other by hydrogen bonds. … 더 보기 All the functions of DNA depend on interactions with proteins. These protein interactions can be non-specific, or the protein can bind … 더 보기 DNA contains the genetic information that allows all forms of life to function, grow and reproduce.
