One new strand, the leading strand, runs 5' to 3' towards the fork and is made continuously. The other, the lagging strand, runs 5' to 3' away from the fork and is made in small pieces called Okazaki fragments. Example: Determining a complementary strand

There are three components of a single nucleotide: one deoxyribose sugar, one phosphate, and one of the four bases. To make a complete DNA molecule, single nucleotides join to make chains that come together as matched pairs and form long double strands.
