3 - DNA Replication I

    Cards (6)

    • DNA replication is the complete, faithful copying of DNA
    • DNA replication is semi-conservative: each strand of the parental double helix acts as a template for synthesis of a new daughter DNA strand
    • In DNA replication, complementary bases are added to bases on the template strand
    • DNA synthesis is unidirectional (5'-->3')
    • Complementary base pairing to the template strand in DNA replication ensures that each daugher double-helix is identical to the parental double-helix so the daughter cell receives identical DNA molecules
    • Chromosome replication is bidirectional and initiates at discrete sites
