Step 1
A nucleotide consists of three main parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. Here's a drawing of a nucleotide: ``` O || P - O | O | C - O | | C C | | C C | | C N | | N C | | N - C | Show more…

The diagram above shows a replication fork during DNA replication. The pentagon-circle structures represent the sugar-phosphate backbone, and the numbers represent the nitrogenous bases. Knowing what you know about the complementary configuration of bases in DNA...if base 3 is guanine, what is base 3'? adenine thymine cytosine
