Which chemical bond (be specific) in a nucleotide is broken to supply the energy for nucleic acid synthesis

Phosphodiester Bond

Explanation:

Nucleotides are linked with a phosphodiester bond formed between the phosphates group present in Nucleotides.

Nucleic acids including DNA and RNA in living organisms. Phosphodiester bond between nucleotide is broken to supply the energy for nucleic acid synthesis and supply energy between the 5' and 3' carbon atoms in Nucleic acids.

Hence, the correct answer is "Phosphodiester Bond".

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.
