Web21 de jul. de 2024 · How are the two DNA strands held together? 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. WebVerified by Toppr.
