2 mar 2012 · The basic structure of DNA involves two anti-parallel strands coiled around each other to form the familiar double helix structure, held together by hydrogen bonds between complementary nucleotide base pairs and base stacking interactions.
11 maj 2017 · DNA is composed of nucleotides that contain nitrogen bases, sugars, and phosphates. The order of these nucleotides determines the genetic code. DNA exists as a double helix structure with two complementary strands joined by hydrogen bonds between nitrogen bases on each strand.
9 lut 2014 · It describes the key components of DNA including the sugar-phosphate backbone, nitrogenous bases, and how the bases pair up in the double helix structure. It also discusses different DNA structures like A, B and Z-DNA and how DNA packages into nucleosomes and chromosomes.
