How dna strands are held together
WebThe DNA bases pair together: A-T, T-A, G-C and C-G. DNA is arranged in a double helix structure. A gene is a short section of DNA that is the genetic code for a characteristic. WebThe two strands go in opposite directions, with the nitrogen-containing bases facing inward to make the steps or rungs of the staircase and the sugar-phosphate backbone making up the outside walls of the helix. The hydrogen bonds between the nitrogen bases keep the two strands of DNA together and help keep the DNA molecule stable and whole.
