Question

this is a model of a dna molecule. which type of bond, denoted by the arrows, connects the nitrogen bases and will be easily broken for dna replication? peptide bond covalent bond hydrogen bond ionic bond

Explanation:

Peptide bonds are in proteins, covalent bonds are strong and not easily broken for replication, ionic bonds are not involved here. Hydrogen bonds between nitrogen - bases in DNA are relatively weak and can be easily broken during DNA replication to separate the strands.

Answer:

C. hydrogen bond
