syntenic genes
genes located on the same chromosome
Linked genes are
2 syntenic genes that CAN NOT sort independently
nonrecombinant chromosomes
Also called parental chromosomes. these are chromosomes that do not reshuffle
recombinant chromosomes
crossover of systenic genes
the further systemic genes are from one another.....
the frequency of crossover increases
Topoisomerase
relax supercoiling (helps separate into SSD)
Helicase (DnaB)
unwinds the double helix
SSB
single stranded binding proteins that prevent reannealing of separate strands
Primase (DnaG)
synthesis of RNA primer
DNA polymerase III
synthesizes new DNA only in the 5' to 3' direction
DNA pol I
removes the RNA primer and replaces it with DNA
DNA ligase
an enzyme that eventually joins the sugar-phosphate backbones of the Okazaki fragments
