The diagram below shows a short polynucleotide chain.

For one deoxyribose sugar, label the carbon atoms from $1\text{'}$ to $5\text{'}.$

Label the $5^{\text{'}}-$end and the $3^{\text{'}}-$end of the polynucleotide chain.

Label the sugar$-$phosphate backbone.

Circle a phosphodiester bond in the polynucleotide chain.

Identify the name of each base and classify the base as a purine or pyrimidine.

Write the sequence of bases for the polynucleotide chain, including the $5^{\text{'}}-$end and $3^{\text{'}}-$end.
