misc biology 1 DNA replication and packing part 2 (DNA replication, 5', 3', anti-parallel, polymera

The DNA  stands is elongating continuously toward the replication fork

when dna is damaged, a nuclease cuts out the damaged strand and a dna polymerase fills in the missing nucleotides and DNA ligase seals the new and old nucleotides

special nucleotide sequences at the end of DNA that do not code for any genes and buffer nucleotides that do contain genes from erosion
