Cell Division
process where celss create new cells
Telomeres
-noncoding DNA
-location: tips of eukaryotic chromosomes
-lifespan: # of times a cell can safely divide
-protective caps
Telomerse Disease
Hutchinson-Gilford Progeria
DNA Replication 2 steps
1) unwinding and separation
2) reconstruction and elongation
Step 1
starts at the origin of replication—> DNA splits into two strands
prokaryotes =single eukaryotes = multiple
Reconstruction and Elongation
proteins bind to strands
DNA polymerase - adds nucleotides with complementary bases
-repairs errors that occurred in DNA replication
