Answer
The type of bond which allows DNA to be readily replicated is 'hydrogen bond'.
Explanation
## Step 1In the context of DNA replication, it is important to understand the nature of the bonds that hold the DNA molecule together. There are two types of bonds to consider: covalent bonds and hydrogen bonds. ## Step 2Covalent bonds are the bonds that tie the individual atoms of the DNA molecule's backbone together. They are strong and stable, making them ideal for maintaining the structural integrity of the DNA molecule.## Step 3On the other hand, hydrogen bonds are the bonds that allow the two strands of DNA to come together to form the well-recognized 'ladder shape'. These bonds are weaker than covalent bonds, which allows the DNA strands to be unzipped and separated during replication.## Step 4The reason why hydrogen bonds are ideal for replication is that they are weaker than covalent bonds. This allows the replication machinery to break open the DNA strands for replication. If the bonds connecting the strands were too strong (like covalent bonds), it would prevent or make it too difficult for the replication machinery to break open the DNA for replication.
