- How is DNA stored?
- Eukaryotic Cells
- linear DNA molecules - chromosomes
- made up of 1 long molecule of DNA & associated proteins
- found in the nucleus
- DNA molecule really long - has to be wound up
- wound around histones (protein)
- help support DNA
- then coiled up very tightly to make compact chromosome
- wound around histones (protein)
- mitochondria & chloroplasts have own DNA
- similar to prokaryotic DNA
- circular & shorter than DNA in nucleus
- not associated to histone proteins
- similar to prokaryotic DNA
- linear DNA molecules - chromosomes
- Prokaryotic Cells
- carry DNA as chromosomes
- DNA molecules short & circular
- not wound around histones
- condenses to fit into cell by supercoiling
- Eukaryotic Cells
