Question

what type of bonds are formed between nucleotides in a single strand of nucleic acid

Answer 1

In a single strand of nucleic acid, nucleotides are linked together by **phosphodiester bonds**. These bonds are formed between the phosphate group of one nucleotide and the hydroxyl group on the sugar of the adjacent nucleotide. This linkage creates a sugar-phosphate backbone that provides structural integrity to the nucleic acid strand, whether it is DNA or RNA.
