WebDNA replication is semiconservative, meaning that each strand in the DNA double helix acts as a template for the synthesis of a new, complementary strand. This process takes us from one starting molecule to two "daughter" molecules, with each newly formed double helix containing one new and one old strand. http://benchpartner.com/q/what-are-pentoses-to-what-organic-group-do-pentoses-belong-are-nucleotides-formed-of-only-one-type-of-pentose
