BIO 2600 Study Guide - Dna Replication, Semiconservative Replication, Complementary Dna
Document Summary
Dna acts as a template for its own duplication: both the s strand and its complementary s" strand can serve as a template to specify the sequence of nucleotides in its complementary strand. Each of the two strands of dna is used as a template for the formation of new, complementary dna. Strand: semiconservative replication: each parental strand serves as the template for one new strand; each daughter dna double helix composed of one of the original 9old) strands plus one strand that is completely new. Dna synthesis occurs at y-shaped junctions called replication. Forks: replication forks are the points at which the dna strands open. The particles visible along the dna are nucleosomes, structures made of dna and the protein complexes around which the dna is wrapped. At a replication fork, the two newly synthesized dna strands are of opposite polarities.
