Final answer:
The bond made between nucleosides in a solution is a phosphodiester bond, which forms the backbone of the nucleic acid structures in DNA and RNA.
Step-by-step explanation:
The type of bond made between nucleosides in a solution is a phosphodiester bond. Phosphodiester bonds are formed between the phosphate group attached to the 5' carbon of the sugar of one nucleotide and the hydroxyl group on the 3' carbon of the sugar of another nucleotide. These bonds are crucial for the structure of nucleic acids, forming the backbone of DNA and RNA chains.
