chapter 11: Nucleic Acid structure, DNA Replication and Chromosome structure
-
Nucleic Acid Structure
James Watson and Francis Crick, Rosalind Franklin’s proposed the structure of the DNA double helix, and Erwin Chargaff did the base pairing A-T, G-C.
-
DNA Replication
Conservative mechanism:
DNA replication produces 1 double helix with both parental strands and the other with 2 new daughter strands.
Semiconservative Model:
DNA replication produces DNA molecules with 1 parental strand and 1 newly made daughter strand.
Dispersive mechanism:
DNA replication produces DNA strands in which segments of new DNA are interspersed with the parental DNA.
