The importance of the nitrogenous bases in DNA having relatively weak hydrogen bonds connecting them strives in the fact that they can be separated easily (Option b).

  • DNA is a double helix molecule consisting of two long opposite strands of nucleotides linked by weak hydrogen bonds.

  • In DNA, Guanine pairs with Cytosine through three hydrogen bonds, while Adenine pairs with Thymine through two hydrogen bonds.

  • The presence of weak hydrogen bonds enables the separation of both nucleotide chains during DNA replication and transcription by enzymes called helicases.

  • Moreover, consecutive nucleotides in each DNA chain are linked by covalent (strong) phosphodiester bonds.

In conclusion, the importance of the nitrogenous bases in DNA having relatively weak hydrogen bonds connecting them strives in the fact that they can be separated easily (Option b).
