Can someone check if this is right please:

Base bonding: hydrogen bonding

Bonding between adjacent nucleotides: ester bonds between the sugar base of one nucleotide and phosphate group of adjacent nucleotide

Reactions which form polymer: condensation reaction in which phosphodiester bonds are formed

Yep they all look correct! However for the third one, just make sure you specify which polymer you're referring to - in this case its a DNA polymer strand since you referred to a phosphodiester bond. If you talked about a polymer sugar (polysaccharide), you would still have condensation reactions but you form glycosidic bonds instead. I hope this helps!

May I ask which exam board you are doing?
