Unlike the strong covalent bonds that hold nucleotides together in the DNA backbone, non- covalent bonds are used to join the two strands. The weak nature of these bonds allows the two strands to be pulled apart for copying without physically breaking either of the two strands.

DNA does not usually exist as a single strand, but instead as a pair of strands that are held tightly together. [9] [11] These two long strands coil around each other, in the shape of a double helix . Ver mais 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 Ver mais Base modifications and DNA packaging The expression of genes is influenced by how the DNA is packaged in chromosomes, in a … Ver mais DNA usually occurs as linear chromosomes in eukaryotes, and circular chromosomes in prokaryotes. The set of chromosomes in a cell makes up its genome; the human genome has approximately 3 billion base pairs of DNA arranged into 46 … Ver mais 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 " Ver mais 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 … Ver mais All the functions of DNA depend on interactions with proteins. These protein interactions can be non-specific, or the protein can bind specifically to a single DNA sequence. … Ver mais DNA contains the genetic information that allows all forms of life to function, grow and reproduce.
