DNA Replication The Chemistry of the Addition of Substrates of DNA Replication While the leading strand and lagging strand replicate differently, each individual nucleotide added to each strand is attached through the same mechanism. In this section, we will examine the mechanism of nucleotide attachment. Note : classes such as AP Biology do not require you to know the topics covered in this section. The Building Blocks of DNA Replication are Deoxyribonucleotides The building blocks added on to a growing daughter strand are individual nucleotides.

Unformatted text preview: Remember, in DNA the -OH group at the 2' position of the ribose ring is missing. As a result, the substrates for DNA synthesis are called 2' deoxyribonucleotides. Figure %: 2' Deoxyribonucleoside triphosphate Attached to each deoxyribose ring is a base group (C, G, A, or T) and a triphosphate group. The three phosphates are designated alpha, beta, and gamma (alpha being the closest to the ribose ring). These phosphates play key roles in the addition of subsequent nucleotides to the daughter strand....
